Is is possible that I have ADHD?

I’m currently in the process of trying to find a psychiatrist for an assessment, but I was just looking for some ideas or advice while I’m still searching.

As an example:
At the end of last year (I’m a college student) I ended up in the hospital for mental health reasons for two weeks. Because of this, I missed several tests and had a very hard time trying to catch up. One of my professors, however, my calc professor, gave me a few options, and we both agreed that filing for an incomplete would be a good fit. I was given until September 27th to finish the class (I have two tests left to take) and was told that it would not affect my registration for the next quarter, which it did. Classes start back September 4th I believe, and I’ve yet to complete the class or register for the Fall quarter, and I can’t register until I finish the class. My problem is that I have been having such a hard time forcing myself to get up to study, and I’m hoping to have both tests done by the 3rd or 4th of next month to give my advisor enough time to add me to calc 3, which is required for my major. Classes need to be paid by the 30th of next month. Every night since summer started I’ve been waking up in the middle of the night panicking because I know I need to get this done, but I just can’t seem to. To avoid doing it, I’ve just been working around the house to take my mind off of what I know needs to be done. I hate myself for waiting so late. I’ve been doing this my entire life, and I don’t know if this is ADHD related, anxiety related, or if I’m just really lazy. I love math, it’s literally my major, so why can’t I force myself to get up to do it? I had so much planned for the summer that I haven’t been able to do because I didn’t want to do any of it knowing that I had not done what I needed to do. My mom’s been asking all summer when I was going to finish my class, and it’s been invoking so much panic in me.

Sorry for the rant, but does anyone have any current advice while I’m in the process of finding a professional? Thanks!
