Waiting for the medications

Hello, I'm new here! I am 26, the suspicion of MS appeared in February of this year, the diagnosis was confirmed in June. Yesterday I was at the doctor who will prescribe me medicines in September, and I am terribly worried because either I will have to take injections, or because of the pills I can lose my hair with a high probability, and I really want to go to another country for a year in a volunteer program and I'm nervous that the medication won't work and I won't be able to take therapy, or that I just won't get help. And in the end, I don’t know how to solve these problems and focus at all. I'm just scared and tired.
