Nursing and Meniere's Disease Help!

I'm a 19 year old with Meniere's disease and I've had it for about three and a half years. I'm doing my pre-reqs for nursing; this summer I had an internship at OHSU and have just fallen in love with nursing and helping people (I want to be an NP). I had surgery three months ago but it looks like it's failing I've been laying around crying all day because I don't want to give up on my dreams. This disease is HELL and it's more hellish if you are trying to be a normal 19 year old who hangs out with their friends, goes to school, works, and just has fun. Any nurses with Meniere's out there? Or just people with advice in general. I feel like if I let my profs know about Meniere's they give me bad grades; which has happened to me before. Or people tell me I can't do it; my uncle even told me that nobody would want to hire me because I take days off, I've had profs embarass me like telling me to take a leave of absence when the disease is permanent, and a family who sometimes gets it then sometimes doesn't. Can you be a nurse with a disability? Or do they not want you to be; are you more likely to be laid off or fired because of your disability or do people treat you unfairly? Any advice or guidence would be very much appriciated!
