Help?

I feel like I need someone to buddy up with and help me get up to a healthier weight. I struggle with anorexia and have been an over-exerciser before but I always feel less stressed after exercising and even my treatment team suggests working out (moderately and with good intentions). If I have to gain weight, I'd rather do it while working out so I can gain lean muscle and not just pile on fat.

I just need someone to help push me the right way and to help me stay accountable. I also need someone who understands lifting because I know nothing about it but still try, however it's infrequent.

So, help?
