Sleep intolerance

I have always struggled with sleep. When I think back to when it started it's honestly been most of my life. I have had different phases of either struggling to fall asleep or waking up throughout the night several times. More consistently though, it is difficulty with falling asleep. I got diagnosed with ADHD as an adult(24yo), just last year, but have had anxiety since I was a child.

It has come to a point where I avoid sleeping because I know when I lie down I'm just going to sit there and think, think, think. If it were up to me, I could easily stay up until 2-3am most nights. It's frustrating because my partner can fall asleep within minutes of laying down. And he doesn't understand when I tell him l'm tired...but not sleepy. I like sleeping, but I do not like going to sleep. It that makes sense...it's translated into my brain now that I simply do not like sleeping. It's very hard for me. Additionally, I find my brain gets so many creative thoughts at night and I have so many ideas. It's like a train on the rails just keeps going and going.

I'm wondering if anyone else struggles with this. I don't know if I have insomnia, or if it's my anxiety and/or adhd. I know sleeping later than you want to is an adhd symptom. I guess I just want to see if there's any validation in this. I could wake up at 6am and still stay up til 3am that night easily. It's such a struggle.

Let me know your thoughts. Thanks <3
