Lostoyou,
you need to talk to people (friends & family) inorder to get their help & understanding (it will take them time, they may feel guilty for not realizing & so on so give them some time & be honest) you need this if you are to recover & you can!!!!
You need to forgive yourself for being human, humans have problems & we all have trouble dealing with our problems, so you have aproblem & you (like the rest of us - regardless of what our problem is) are having trouble dealing with it. God made humans with a need for companionship so that we could help each other, we're not meant to solve & deal with our problems alone.
There are also support groups.
You need to eat, but you need to keep it down, so first figure out what you're prepared to eat & start there, take baby steps to eating properly, don't expect yourself to just be able to jump in & eat full meals, allow yourself time to heal & to get used to eating slowly. Try & make what you do eat though healthy - fruit, vegetables, chicken, fish etc.
Ok, so life is terrible - what are you going to do to make it better??????
Try going for a 30 minute (gentle) walk of a morning, do some meditation, relaxation or yoga, listen to music, go out with friends, find a new hobby or get involved again in an old hobby & make friends or renew them. In other words put some fun stuff & some relaxing stuff in your life.
