hey,
i just want you to know you arent alone. you could throw a rock at this forum and hit atleast one person who you will be able to relate to!
im sorry you are feeling the way you are right now. it really does get better though. im prob not the best to be giving advice because im trying to get back out of my current situation, but when i was doing good, after a while it was so nice to finally start to feel all the possibilities again and what life can offer.
be strong, its only been 3 days, the first week or two always suck the most!
