I am very sorry. I understand you like no other, because I feel the same. Sometimes such a strange exercise helps me : I put before a some simple goal, for example, take the twine for a week, and every day I train on this till I find what I wrote. Goals can be completely different - read a book, watch a series of films, river, mountain climbing, learn to play a new song on the guitar... Important constantly to do it, to observe the discipline. Such an exercise advised me to my therapist, and to me it really helps. Hold on, everything will be fine!!!
