Why am I treated this way? What did i ever do wrong to deserve this?

This is a perfect example of Murphy's Law. What can go wrong, will go wrong. The thing is, people only notice the bad things that go wrong. For example (this is kind of random), but pretend you're in a car stuck in a traffic jam. You notice that the lane next to you is moving faster than you, so you pull into that lane. Then, oh no, you notice that the lane you were previously in is now the one moving faster! Yet somehow, you still manage to get to your destination.
People only notice the bad things. They seem to forget about the good things. Hey, that other lane may have been moving faster, but you got where you wanted to go, didn't you?
Take joy in the small things. Don't be pessimistic.

You sound depressed.. Talk to someone!

you definitely should find someone to talk to... family, friend, doc, perfect stranger staring crosseyed at a bottle of jack... someone anyone who can get to know you better than someone only reading those few lines cause i cant know u enough to point out the good things you dont see... quit looking so deeply into all the bad stuff cause life is tough find the good in life... i dont mean to preach so sorry if you feel that way but talk it out with a freind
