Do you tailor your life around your brain and differences?

I don’t know how to word my question. I’m in my second year of uni and I’ve been thinking of applying for an internship. I have ADHD and OCD and I’m on the bipolar spectrum. I’ve been on medication for about four years now. I have my ups and downs but I’ve reached stability recently. But still, I’m hardly passing my classes (cuz I don’t like my major that much) and I feel like I’m falling behind people around my age (I’m 19). My mom thinks it’s not necessary for me to joggle both work and uni because my mental health is already fragile. She says I need to focus on graduating first. As much as I know she’s right, I hate to think I’m actually that weak. I don’t know if it’s right for me to accept that yes, I am different from most people and I have to go the extra mile to ensure my mental health comes first so my path is not that clear like normal people, or that I should just suck it up. I know it’s possible for people like me to improve and get to wherever they like, and I know that I have so much potential, but I’m afraid that I’m not that brave and have an extremely low self-esteem and I will forever hold myself back and the fact that I have issues and use meds will take its toll on me. Is it right to consider that my brain is wired differently or does that count as just making excuses? I don’t know if I’m making sense but what should I do? Should I look for internships? or do I make sure to graduate first?
