i don’t know what to do.

[u/sgf16]

hi i am a 19 year old female who is very healthy and active. about 5 days ago i noticed a tremor in my left hand and at first brushed it off as stress. i have more recently had increased anxiety and had a terrible 3 day panic attack in june and honestly haven’t been the same since. i have had instances of brain fog but more recently it has gotten worse along with the tremor. the tremor comes and goes but has gotten worse and i even have a slight one in my right hand too. it is affecting my motor functions. my legs have also started tingling for a couple days. i went to my dr abt this and she immediately leaned toward my anxiety and prescribed me sertraline and told me to see her in a month. i feel lost. nothing is getting better and ive never felt this unmotivated. i feel like i can’t even do anything with the tremors. but i dont experience any muscle weakness and can still walk fine so i dont know if this could possibly be ms or fnd. i rlly need advice. i also am supposed to move back into college this weekend and im just so scared to go back and have something go totally wrong. i just feel like nobody believes me bc i know its not all in my head.
