Personally I believe that the urges never completely go away - if you become stressed enough and your coping mechanisms stop working then the urges can always come back. But a year is a great achievement and you can get there again.

It sounds like you have been through a lot of stress this year and I can completely understand why you are struggling. I'm sorry you have been through so much.

I can promise though that in time it does get easier again. The issues causing the stress do pass or get easier to manage and the urges subside as well. Hang in there

Can you remember some of the things you did to help manage the urges last time you stopped SI? Some of those things might help now.
