Please don't cause yourself any more harm, remember how upsetting it was before when you realised the damage you had done? If you need some support please keep asking for it, don't take any drastic actions. Do you know what you want to say at your appointment with the CC? Maybe you could try and prepare for that.
You've managed well with work despite all the things you were going through at the time. I think if you found a voluntary position in an area that you're interested in you might feel more relaxed and get some enjoyment from it.
