How do you know if your emotions are depression, meds, CPTSD, state of the world, a genuine issue that needs addressing or what?

I'm really struggling right now. I had to go on disability for six months and a partial hospitalization for two weeks because I started crying and didn't stop. While there, they put me on Cymbalta which felt like it made the depression worse. Now I'm on Fexima but they're playing with the dosage. I also am getting over a two-week flu. So IDK if my intense sadness (and nausea) are that, the crazy state of the world, being back to work, the work I'm doing on my CPTSD or what. I've been messaging my new psychiatrist every week, but I'm not really getting any responses.

When I say, "depression", I don't mean "kinda sad". I mean full-on physical symptoms like a pressure on my chest, trouble breathing, neck and head pain, stomach like a ball of lead.... Grounding and DBT are barely doing anything. So how do I know if this is my "normal for now"? Does it matter? Should I demand to go up on meds so this goes away?

FWIW, I was raised that only weak people go to doctors. So it's really hard to advocate for myself without a ton of research to back up what I say.
