First off, congratulations for going over 2 and a half months without SI! That is a great accomplishment in itself. I have gone about the same amount of time. Go us!

This sounds like you are in a crisis situation. During a crisis, there are coping skills you can do to get through each day one at a time. I have been there, and had depression for years, and I still get it on and off. My diagnosis is schizoaffective disorder, bipolar type. So i definitely get depressed. One skill I use is "opposite emotion" which is a skill from DBT therapy that I am in. This means that when you feel one emotion, do something that is the opposite. For instance if you are angry, listen to calm music. If you are depressed, watch some funny videos on youtube or on TV. For me, I get upset, and I watch Family Guy on the TV. It helps me. Just doing little things like that could help you too. it is ok to be depressed, and don't try to fight it too much. Do these little things but also know that the depression is not going to kill you. You can get through this without SI or suicide. And you will. I am not going to tell you to go exercise or any of that. If you can, that's great. But I know thats the last thing I want to do when severely depressed! I need simple things I can do very easily. Like turn on the television, or get online and talk to people. Talking helps me a lot. Take it one hour at a time if you need to, or even one minute at a time. But tell yourself you will get through this. It will not last forever, and all you need to do is get through 1 week. What skills have you used in the past to not SI? Keep doing those. Ultimately you know what works for you. How did you get through yesterday? Do that today too.
