I don't know that this will help at all but just what popped into my head as I read this today. when you mentioned being kind of stuck what popped into my head is some kind of change or action that would take you out of the midst of overwhelming thoughts of everything right now when clearly you're probably spiralling and spinning your wheels a bit. (just my interpretation of what's going on)

What do I mean? i dont' know what would work for you and I don't have any idea what options you have available to you at the moment. Examples that would work for me in this type of situation is getting out, doing something either you haven't done in a long time that is relatively mind freeing or something you've never done that will take all of your energy and thought resources to do. For some it could be a place, for others it could be an activity but I think the key here is it has to be interesting, and appealing enough that you would be taken in by this "thing". I am not sure if I'm making sense.

I gues the best example I have is that I just got a tattoo. Never had this done. it was a different experience and no I'm not suggesting you do this but bear with me. It was a different environment, people I'd never dealt with and for me it's relatively stressful, which could be bad but it wasn't. It tool all of my attention and energy to deal with new people and going through the experience itself was enough that I know had I been in a bad state or even "stuck" it would have brought me out of it. I know I came out of there very relaxed and happy with things. And although I wasn't particularly doing badly I know it is something that would have helped me if I hd been.

Maybe I'm talking from left field here but just what popped into my head.

Hope it helps, S4
