What does ADHD look like in adults?

I’ve had ADHD since I was a kid and I don’t honestly remember struggling so much as a kid. I didn’t exceed in school I got by, I was great at sports , and when I wasn’t playing a sport or at school I was playing video games. Now that I’m older I can’t hold a job, I get fucked up all night and I’m just not one of those people who can get fucked up and show up too work the next day hell I might miss two days in a row from getting fucked up for one day. I make appointments and just don’t show up , I might not even call work and tell them I’m not coming I just won’t show up. With all this going on I do have a regular fitness routine and I stay in gym but I just can’t seem to cope with life. If I’m not in the gym I’m getting high and drunk all day. But I don’t wanna get high and drunk anymore something just feels off
