severe sleeping-apnea ("brain incuded") - No energy at all, I'm at a loss

[MrMustard]

I'm 25 years old. I've been suffering from chronic fatigue for maybe 6 years, constantly increasing in severeness. now 6 months ago I was finally diagnosed with sleeping-apnea, it's totally atypical, comes from the brain, the doctor said. I've tried machines, didn't work, I tried valerian, that only further reduced my blood pressure, which is already very low - i also suffer hypotension.

now i don't only suffer from bad breathing at night, also during the day i feel like not getting enough air and not being able to breath properly. i tried meditation, didn't do much. currently I'm in therapy, only talking. I do know that i have emotional issues, i do talk about them but it's not really changing.

I really don't know what more to do, my energy levels are so low I don't do anything all day, had to move back in with my parents cause I got too tired for everything.
I do exercise, however, it makes me more tired, even the next day (jogging/swimming).
