Struggling with ADHD in Nursing School

I’m really struggling with school and everything lately and I feel like nobody understands. I’m always late to class and today I was 20 minutes late to clinical and my instructor was asking me why? And it’s like, I don’t know! Maybe I’m just a failure? I was up all night finishing the worksheets that were going to be due when I got there so that’s how it happened. And I saved these worksheets until last night because this clinical was overwhelming and I was scared to look at what I had to do for it. And then I looked just a day ago and I actually had kind of a lot to do and I almost ran out of time. It’s really hard that I can’t get any accommodations or any understanding or help for being late or having late assignments or anything, these are all problems because of my ADHD. It’s not just because I’m lazy or I’m an unprofessional person and a bad worker. And it’s hard that I have to go through all of the schooling when the job is never this hard on me for timing/executive function. (I’m in nursing school). It’s hard that I get marked down for professionalism, but it’s really just that I have poor time management. This should be something that is accommodated for because I have a disability. And I know that I’m losing points and looking bad when I am late and not finishing my stuff so I feel like I’m not just “using my ADHD as an excuse”, it’s just a good explanation for my huge struggles in everything. This is just so exhausting. I got an F on an assignment and the instructor wants to meet with me to discuss, but there is nothing to discuss! And I feel like they won’t understand even if I explain it to them how hard it is for me because they just need me to be more professional and remember that I would get fired if so did this at a job. I know. I just feel like I’m going to fail at least one of my classes this semester and I’m going to have to stay back a semester. Which is fine, but it’s just more money and more time having to be in school that I hate, and waiting longer to do something that I actually want to do. If you have read all of that I appreciate you so much please comment anything to make me feel less alone.
