i also wanted to add that i suffered very intrusive thoughts - ocd, hurting myself/others etc - which i found very distressing - i used the same approach with these too and i can see them for what they are - just thoughts.

2 weeks ago i was getting a couple of hours sleep a night at the most, could not eat, lost 1/2 stone, heart racing, brain racing so fast i thought i was insane, nothing made sense, depersonalisation, shaking and panic so bad i could not escape for a second - acceptance has improved them 90% in 2 weeks!!!! but you need to keep going - EVERY time you feel a stab or wave of fear - or think a negative thought - you need to reassure yourself, talk nicely to yourself and simply accept it - it will ALL LIFT!
