I feel so lost and hopeless, what should I do?

Everything feels pointless and meaningless. Everything in life is going down hill and I got nothing going for me. Ill never make enough money to live on my own let alone ever own a home so ill never be able to build the garden I've always wanted to. I can never seem to get good enough at anything I do like I can't learn at all no matter how many hours and hours i try every single day.

I want to make good art but i can't ever seem to get better at that, im not even good at the things i try to enjoy despite spending many years of my life trying to do these things. I can never hold down a job cause im again not good enough at anything and will always mess something up to get me fired somehow.

im 23 and I got nothing. im not smart or skilled. my reaction time is over half a second for visual or audio. Im colorblind, autistic, and ADHD. I try so hard to get better at anything and I can't ever keep something going. im always hitting a wall with everything I do. I've drawn and painted for years and im no better when I started. I've tried to learn languages but the moment i dont practice for a day or two i forget everything I learned. I can't memorize anything at all.

With all this on top of the world getting worse and worse day by day even if i somehow got a decent job that payed 60-80k a year ill still never own a home cause who know. 10 years later houses that were 400k today now are 1m. pay will never go up and everything will get more expensive until i can't afford to eat anymore. I can't write for anything and im bad at school no matter how many hours i devote into anything. Im always failing my family and friends, im not a very good DM for my friends no matter how many hours i put into practice. and before anyone says anything no, i can't get anything to help with my ADHD despite how much i want to cause its just too expensive. I'm lost.
