I think I can relate. I have days when I can't figure out how I'm feeling, but it's something of a mix. I'm short-tempered, unable to relax, pushing everyone away (meaning my pets - can't have them near me, can't do physical contact). Not pleasant company at all - to anyone else or myself. And like you describe, I can't seem to make it better. Usually it just runs it course.
Sometimes I have the sense that something specific is hiding underneath it all. Something that might help me regain my balance, if I could only realize what it is. Naming emotions and putting feelings into words is difficult for me; "not doing well" is about as succinct as it gets.
I'll try to describe what sometimes helps me (haven't done so before, and not sure I can do a very good job): I find "my inner bench" - an imagined/visualized bench in an calm and secluded area (forrest, lakeside, meadow whatever seems best). On this bench I usually find someone sitting; someone who represents what it is I am not seeing/feeling clearly. I have often found a young girl with her knees drawn up under her too big shirt, arms wrapped around the legs and her head bent down, shielding her face. Sometimes she cries, sometimes she is shaking with fear. What this gives me, I think (it's still new to me), is a direct line to whatever it is I am unconsciously avoiding realizing. Sometimes this insight can help me better focus on what is really bothering me - and gets me one step closer to finding a way to decompress. Sometimes just witnessing the scene and acknowledging what I'm seeing/feeling calms me down.
I can't always go to the bench, and anyway touching is a no-go, but I have tried having a beloved pet sit next to the girl on the bench and offer support/validation/comfort, which has also helped calm me down.
Don't know if any of that was helpful to you.
