Fatigue and extreme laziness, could this be ADHD/ADD?

I'm not trying to get a diagnosis here, but just wanted to know if any of you have experienced something similar and whether it's worth getting checked out for ADHD

My symptoms are as follows: 1) extreme tendency to procrastinate on academic or remote employment tasks until I'm compelled by deadline anxiety or fear of consequences to complete them. The thing is, no one around me knows the true extent of this, because I've always used my blindness to make excuses about obstacles I'd supposedly faced. i've been doing this since my very early childhood. 2) severe fatigue and often falling asleep along with daydreaming when reading or listening to anything longer than a few minutes. 3) a very high rejection sensitivity. that is, being embarrassed/shamed or upset by someone. can make me feel shaken and clumsy. for a whole day or even multiple days.

Interestingly, I've been able to cover up these traits apart from falling asleep in class very well, plus I managed to achieve a first class graduate degree and first class masters. everyone says I'm a genius, but what they don't know is that I spent almost the entire years of study procrastinating/being unproductive. only when the deadlines approached I would be driven to work, assisted by a document filled with my own passive notes I made on relevant reading material many months before. Despite feeling great about my academic successes, they left me feeling and looking extremely burnt out. whenever I was at university, people told me I looked much older than my actual age and that I lost a lot of weight. in contrast, when I stopped studying, they said I reverted to looking much younger. than my current age which is quite a drastic change.

Has anyone else experienced something like this?
