when you're writing just dont stop, it can be easy to think you're writing too much but it's not a problem, the more you write and the more you get into it then odds are you'll notice things you hadnt before, ask them for a contact email too that you can mail them personally any time, it's not always the reply thats important, just the ability to say how you feel, the more you can be open about, the more weight off your shoulders. Eventually you can start challenging yourself bit by bit, but not until you feel ready, my gf went through similar things and now she's usually alright, she has bad days, but much better as a whole and far more confident
