what if i can’t handle my dream career path?

i’m starting cosmetology school in like 3 weeks and since like maybe march of this year i’ve been fighting with the school to agree to give me the accommodations i’ve asked for. these accommodations include being able to sit if i need to, being allowed to use the bathroom when i need to, and having unlimited access to water and snacks. not too much to ask for right? the only thing they’re not giving me trouble with is the bathroom thing. every time i go through and explain my accommodations and how they help me, i get excuses as to why it’s just not feasible. i’ve explained that i can’t stand for long periods of time because it’s painful and that if i’m not eating and drinking throughout the day i get dizzy and lightheaded pretty quickly. i also provided documentation from my doctor explaining why i need them. i even said that i understand that i probably won’t be allowed to sit down if i’m working with an actual client and i’ll just push through it. the school is acting like i’m the first person ever to ask for accommodations and they’re honestly making me feel like an entitled bitch for even asking. i’m just worried that without my accommodations it’s gonna be too much for me and i’ll have to drop out, and then i started wondering if i made the wrong decision to be a cosmetology major. i’ve loved hair and makeup since i was 10 years old and have wanted to make that my career for the longest time. i’m wondering now if i should’ve just given in and gone to normal college because i won’t be able to physically handle being in cosmetology. this is something i’ve always wanted to do but now it feels like the odds are against me
