I've been in a shit spot for about a year now, main thing I can say is just talk and spend more time with family friends/relatives. Whenever you're in a real dark spot it helps to be around these people as you start thinking about what these guys will think if you were to act on any of these thoughts.
There were many moments when I never thought I would be getting out of this but slowly I have been improving, if you're really down about yourself write down little achievements that you have done throughout your day, this way you have something you can reflect on to see visible progress.
I've already started to see some as going from not eating for full days at a time, skipping meals etc. I'm now starting to consistently eat more most days. This kind of progress really helped me and will help you knowing that you can make progress and start feeling better about yourself.
