A Sunnah Muslim's struggle with missed prayers

As a Muslim striving to follow the Sunnah, I've missed prayers for 2192 days-that's after rounding up. I'm not even counting the random days when I did pray or the months before my periods started, nor deducting the weeks during menstruation when prayer isn't required. Even though I have a period monthly, I'll assume it's every two months and subtract five weeks per two months, which reduces it by 180 days. So, I have 2012 days of prayers left to make up. If I start from June 2026 and make up all my past prayers while having 5 days of menstruation each month, when would I finish? What if on four days a week I do two past prayers plus the current one, and the other three days just one past prayer with the current one? Now I struggle with OCD, which makes me rush my prayers. I've been doing them quickly ever since I started praying again this year. I fear if I don't do them, I'll face punishment because I didn't have OCD during the six years I didn't pray, and I'm constantly battling intrusive thoughts about faith. So when I overcome my OCD in the future, will I still need to make up these prayers? Do most scholars permit skipping them? I could perform the prayers while ignoring the thoughts, but I'm really tempted to finish them quickly, and I might rush because I genuinely lack patience. What about the prayers I've been doing this year but rushed until now? I didn't have OCD at the beginning; the prayer-related OCD started a month ago. I've had general OCD for two years, but it wasn't about prayers. Before it affected my prayers, I'd already do them very fast. Now, I'll try to do them at a moderate speed, but still... Sometimes I've moved or spaced out during prayer, or forgotten to rinse my mouth after eating. May Allah ease this journey for me and grant me patience and sincerity in fulfilling my obligations.
