Nobody here expects you to follow all the advice given. But there has to be some nugget of an idea that might help you. For example, distraction is a good coping skill. I am going through a very, very difficult family situation. I need to occupy my brain without obsessing over the situation. So I started learning Spanish from a free online program called Duolingo. It takes about 7 minutes per day (I can that you can make it less even). It really helps me a lot.

I'm not saying "go learning Spanish". I'm saying find a coping skill, just one for now, and use it when you get overwhelmed, or better yet when you feel you might become overwhelmed. Once you have one coping skill try to find another. (Or find other ways to distract yourself. As I try to come up with other suggestions I'm just coming up with distractions. Guess what my main coping skill is?). There are a million options out there and right now my clozapine is preventing me from thinking. Maybe someone else can add something or you can.

It's just my take that you get overwhelmed, you come here, you get more overwhelmed, you get more overwhelmed, etc. and that's just not going to help you. You really don't have to do anything big, just a little change for a few minutes per day can help.
