I have 5 things that I'm diagnosed with, but the ones that affect me the most are ocd, depression, and maybe cptsd (idk if I have cptsd, not diagnosed or talked about trauma with my psychiatrist, but I have trauma that affects me a lot).

Back to the title. My disorders become 10x worse because they feed into each other. For example, if I need to do my shower compulsion, it already takes a lot of effort because of depression. But I'm also limited with the time I take a shower at. Because of trauma, if my parents (notably my dad) are in the house, I just freeze and am stuck disassociating. So whenever my parents are at home, I don't end up showering 95% of the time.

As I result, I barely shower. Because of my ocd and having to shower before doing anything enjoyable, I can barely have fun, which makes me more depressed, which also makes me more likely to disassociate.

That's only one example, this affects me in almost everything I do. I feel like a useless old person who sits infront of a TV counting down the days they have left. That's essentially what I do, except for doing a little schoolwork here and there (hopefully my efforts are enough to pass atleast one of my classes).
