I've known my friend, who we'll refer to as M for a little over a year; We both share some of our problems and try to help each other as much as we can. He told me that he was having issues with eating, and I tried to help, giving him things like 'If you've having problem having larger amounts of food, try cutting it into smaller pieces and using water to get it down easier.', but he later told me he was still purging food. It's really affected me especially during quarantine, his dad died in late October and it really affected him, he was exercising a lot more to burn the very little calories he was consuming.  


I've really grown close with him and I feel like shit knowing that I can't help, I've recently started self harming again, before it was with a can and this time I've started using a knife: I wouldn't say it's that bad, if I get mad at myself I'll usually go into the kitchen, pick up the knife and gently run the tip down a part of my arm. A few days after Easter, I had a mental breakdown and I didn't tell anyone in my family, whoever's reading this.. Could you please give me advice on how to help? Anything would be greatly appreciated.
