I second the above posters.
I graduated 4 years after the freshmen college class I started with finished. Whatever. It means nothing when you graduated. What matters is, if you want, it that you do?
I started graduate school at a local uni in my mid (leaning towards late) 30s. I even had a jerky psychiatrist tell me it was a bad idea at my age. Again whatever. I am pursuing a degree in something i want finally. So what if it took some time to get here or it takes me more time to finish.
Forget any time table that society or friends set. You take care of you. Taking care of you means first you take care of your health.
If you are in the USA, you need to register with your uni or college to get academic health and/or disability accommodations. They exist for a reason: to help you to do your best and not sacrifice health, safety, etc to do so.
Don't be afraid to email your instructors. They are human beings, putting on pants one leg at a time and all that.

Best wishes with whatever you decide is healthiest for you,
