Understanding Things...well trying to understand

Well...I have many things on my mind and alot of it's the same old/same old story.  It's like a big circle.  Just goes around and around. And maybe part of it is that I just can't let things go and let the past there..in the past.  And also I can't let people go.  I mean I try and try to be friends with people who don't want to be friends with me.  Why don't they want to be friends?  I just don't understand. I also don't understand how some people say they are Christians, but then sometimes they just don't act like they are.  I mean I am not perfect, but I try to be nice to everyone and friend them and let them follow me on different social networks.  I try to treat them like everyone else.  But there are a few "Christians" who act like they are better than everyone else and won't be friends with me.  Or they will approve me and when I comment/like their stuff all the time and try to be a good friend they just go and block me.  Why?  I just don't understand.  And I know I should let them go and move on.  Forget about them, but sometimes it's hard and I just want to make new good Christian friends.  Why can't they understand that?  What is wrong with me?  Or is it them?  I really want to give up on them and hate them for hating me and blocking me and not wanting to be my friend.  But then I think about myself and how I say I am a Christian. And I want to grow in my faith and relationship with God and Jesus.  So if I hate them..then doesn't that mean I am just the same as them?  And not really a true Christian?  Would God want me to keep trying to be friends with His other children?  Or since they seem like they don't want to be my friends, would He want me to still love them? Even if we never talk?  Still care for His family?  Would He get mad at me for hating some of His Children? Also..another thing that I am so confused about is...People who are gay/lesbians.  Don't get me wrong..I have nothing against gays and lesbians.  Two of my friends are gay and are married.  And I would do anything for them if I could.  But there's the whole thing in the Bible about God made man and women.  And man and woman should be together. So would He be mad that people of the same sex are together and get married?  And is it wrong to support that kind of relationship and be friends with people with that lifestyle?  Or would God still want you to care for them and be friends with them?  Treat them like you would anyone else?  I'm sure God loves everyone the same, no matter what they do or choose to do.  After all, He created everyone and everything.  He knows everyone's life day by day...so He would know what people would choose, and in my opinion, He loves everyone no matter what. He doesn't discrimate against anyone.  But I am still confused on so many things.  I know what the Bible says and I try to follow everything in it, but then certain things come up and I question it.  I shouldn't but I do. And I wish I knew for sure whether or not pets go to Heaven.  I mean people say they do and then someone told me I think and I kind of think it to. Why would God give animals for pets and let you get so attach to them for a few years and then take them away and you never see them again?  I mean if people go to Heaven, I think pets should too.  Because some pets are more than pets..they're like family..kids.  And last year, July 29, 2012 I lost my best friend who was like a son, Jasper.  He was the first real kitten that was mine.  We had other cats, but Jasper was mine. And I had 10 great years with him, but it doesnt seem like enough time.  But we spent so much time together in my room, out in the living room, outside..and it hit me really hard when he passed.  And like I said he was like a best friend, and son.  So it would hurt so much more to know that I will never see him ever again.  Even when I get to Heaven and he's not there.  I don't see how God would let you get attached to someone and then let you never see them again.  I wish someone could tell me this for sure..that I will see Jasper again.  I mean, yea, I have Eli.  But Jasper was a great cat.  He wasn't as hyper or bad like Eli is. He was much calmer.  Eli, like I kind of just said earlier..is hyper, bad, mischevious at times.  But he does make me laugh alot and will lay next to me and sleep next to me or above my head on the pillow. But anyway...there's more I don't understand, but I guess, I really shouldn't go into every single detail and problem I have.  These are just few of the main things I  don't understand. 

Well, not much else is going on. Nothing too exciting. Work is going good.  Need to really take my time and double check everything so I don't make mistakes. I have been playing with Eli, reading, writing, working on my photography page, watching TV and movies. Last Sunday I started to get a sore throat and by Monday it really hurt.  Tuesday it hurt some more.  Wed, wasnt too bad, but then I got a cold and a small sore throat.  Same Thurs. My cold and throat was bothering me.  Same Fri.  Sat..it wasn't too annoying..the cold.  But then my eye was bothering me and of course I kept rubbing it.  And during the night and early this morning, it got swollen and gross..Well now it's still alittle swollen, but looking much better.  Probably got something in it and irritated more.  I hope that is all.  I just want to fast forward and move on.  Get to a day where I actaully feel 100% and have nothing wrong with me.  Guess I will end here...
