Is dspd higher in people with adhd & ocd

I have both adhd and OCD, both severe I leave them unmedicated because I’m terrified of medication, I have struggled with my sleep my entire life and just now finding out about dspd and everything is starting to make sense, I fit all the symptoms:/ I have tried literally everything to maintain a normal sleep schedule even abusing drugs and alcohol, trying to stay up 24+ hours to regulate my schedule etc, but no matter what I cannot sleep until my body is ready and even then my schedule always drifts it’s been as bad as falling asleep at 9am and waking up at 6 pm, right now I’m at 5am - 2pm, very occasionally I am able to kind of fix it some where I’m able to wake up at maybe like 11 am for a few days but it continues to drift and some nights I just genuinely lose the ability to sleep at my normal time. It’s kind of just became part of my life and my whole family/friends know I have a messed up sleep schedule, what can be done about this!?
