welcome Sara! Sorry to hear youre in a bad spot right now-but it will pass.
I dont think its necessarily true that everyone looks to someone for just "what they can get for themselves." this isnt true sweetie. There are decent people out there-youve just come into contact with some real jerks.
Dont worry things will change for you-have a brighter outlook and or change your circle of friends or expand it...not all of us are selfish...you'll find some great people in here who can help ya out with things...
Have fun in here!!!
everything happens for a reason...beginning to wonder why.
