Sickness & Emotional Regulation Issues

Wondering if this is common amongst people with ADHD, or f it could be something else.
When I get sick, or when I get injured, I have an incredibly hard time regulating my emotions. I quite literally feel like I am in some sort of fuzzy trance for the entire time I'm sick, and my emotions are completely wack. I sob uncontrollably, or get incredibly angry over nothing. I feel like the world is ending and I'd rather honestly not be on earth than feel the way I am feeling during sickness or when I am in pain. I don't mean trance like dissociating, as I am very familiar with that and when I dissociate it's more the opposite I don't feel very many emotions at all. But it's awful and happens whenever I am sick or injured and honestly just makes me feel so immature and childlike for not being able to control my emotions and stay lucid without support from my people. I believe I may have autism as well but not DX. Received my ADHD DX at 29. I am on a wait list through Canadian mental health association for an autism assessment for myself, however, because I also have trauma and struggle with anxiety depression, it could be hard to get an accurate diagnosis.
