Uncontrollable outbursts (I’m very confused)

Ok hi. This might be a tad long. So, I have anxiety and depression but I’m being treated for them with therapy, medication, and overall taking care of myself. And for a year and a half I lost my period/it was super irregular. But it’s finally totally normal again (4-5 months now).

And lately (past few months) I’ve had this thing, where I feel like the world is on slow motion and I feel utterly empty for 24hrs and then out of nowhere something swells up in side me and I (in this order) hold back tears for 1hr, cry(but I don’t necessarily feel depressed), my breathing becomes irregular (but it’s not a panic attack), I overheat (like I’m drenched by the end of these), and become really angry. Then I literally need to lie on a cold floor in just my sports bra and underwear. And the anger part lasts the rest of the day.

But I know what a panic/anxiety attack feels like and that isn’t it. And I didn’t really feel depressed. I tracked them for a few months with my period and these attacks don’t line up, they’re completely random. Idk help.
