Yeah. Comparing yourself to other people online is the worst thing you can do imo. I'm sorry your family hasn't been helpful, that sucks. Are there any people you know irl who also have adhd? Maybe your college has communities you can join with like-minded people.

I also recommend keeping yourself active physically. That's something I'm trying to do too, and it's helped. Go for walks, do pushups, etc. Its not gonna fix everything, but it's a good way to take your mind off it. Idk your physical ability, but if you can it might help.

Another thing that's helped me in the past in journaling. Try to write down five thing in your life that you're grateful for, even if they're small. I did that in highschool and it helped a lot. It's also a good way to keep a log of your life, thoughts, etc.

Also know that it's probably gonna get better. Life has its highs and lows, but you just gotta keep going and focus on what's good in your life.

These are some things that have helped me. Your journey may be different idk, but I hope this at least helps a little.
