I completely agree with falsememory. There are a lot of people here who care and are always here to listen or offer a virtual shoulder to lean on when you need us
One thing I learnt recently is to always prioritise. It SI is the only thing you can think of that will help stop sui thoughts or actions it is in many ways understandable - it is a coping mechanism for you when everything else you try to cope fails. But it won't always be this way. In time, the stress will ease again and it will be possible to manage the urges again.
Can you talk to your doctor about how much you are struggling? They might have some suggestions on how to help and get you through this.
Also, I found when I was really struggling again I would still try distraction and resisting the urges but break it down a lot more. If I could stop for 30 seconds when the urges hit the first time that was good. Next time I would try to resist for 45 seconds. And try to slowly build up from there. It might not sound like a massive thing but it helps your brain to process some of the pain and realise that you can survive periods without SI.
Hang in there
