Hi, Bixbite!

Welcome to NeuroTalk!
Well, I think I am safe to say, yes, we've ALL been through much of the same as you. It's hard, it's frightening, it's discouraging, it's frustrating, it's time consuming, and it's necessary.
I was 19 when I was hospitalized for 6 weeks and told that I was anything but ill. Dozens of tests, etc. They even put me with a psychiatrist— I told him to fix me, I had to pitch in the playoffs in a couple days! When the exacerbation ended, I finished college, went on to a good career, and had a wonderful time of it. I didn't get hit hard again until I was 31, then, the hard hits started coming more often for me.
Your neuro is wrong, fire him and find another one. I'm guessing you're not quite 21 and this is no way to live. I honestly, sincerely, passionately hope that you do not have MS, but, if there is something neurological going on, you need to identify it.
Don't give up your life, don't plan on losing all before you've begun. Plan on finding the right "fit" with the right neuro who will address you as a responsible adult and help you formulate a plan. Period.
No doctor ever has a right to treat you like a fool. Ever.
