DAE - does anyone else have problems with memory, finding themselves wandering mindlessly and have strong derealization even though you’re young and physically healthy?

I’m 19 years old work in construction and am tired of being the stupid guy at work, I can’t stop forgetting basic things or not being able to do seemingly intuitive tasks even when I’ve been shown how to do it multiple times. I’ve noticed it’s been getting worse and I even find myself wandering mindlessly and snap out of it once my body realizes what it’s doing, don’t have anxiety in fact my derealisation makes me the exact opposite of anxious. Don’t do drugs or drink and I get an adequate amount of sleep although some days I’ll only get 6 hours. Happens when I’m at home too. Wondering what this could be a sign of and if I need to ask a doctor or something? All of the things I forget or do wrong I know how to properly do but it just slips my mind when it’s time to do it. Also often can’t find the words I’m looking for when I’m having conversations with people.

Any insight would be greatly appreciated thankyou.
