Not much to go on, get evaluated by a psychiatrist and then work on getting either or both medicines or therapy to help you manage it.
Unless you have something more specific that you can say about why you think that you have ADHD or if there's something you need help with, that's about as far anyone can tell you.
You aren’t lazy. Laziness is just a term we use to shame people who aren’t doing what we want them to do. There are always reasons people don’t do stuff.
For people with ADHD, it’s often down to executive dysfunction. But there are other reasons.
if you don't want to/can't go to a psychiatrist, the book "Driven to distraction" was recommended to me. I think it was quite good for me and my partner.
Find some ADHD resources. See if the techniques and tools help, or at least feel sensible. E.g. the book How To ADHD or various Youtube channels.
Seek out a psychiatrist to assess you. It may or may not be ADHD, but something is bothering you that needs attention. They are usually good at figuring that out.
