I feel like my body is slowly failing me

Content Warning: I vent about my health issues.It's been about a month since my diagnosis. Since then, it's been a whirlwind of tic flare ups, medication trialing, an upcoming appointment for injections, and overall general distress. Suffice to say, I have not been having a good time of it. I'm worried that my body isn't handling all of this very well. I'm having bouts of heavy fatigue. The medication for my tics (that I'm now tapering off of) sedates me to the point of passing out. At points, I have random waves of nausea and vomiting. I'm out of breath so much more quickly, and doing chores and errands drains me to the point that I spend the next few hours resting. I can barely do my chores, sometimes I have to leave work early or call out sick. My body will have aches all over, or have reduced sensation. My feet are in such pain every morning that I'm limping. I'm trying not to lose hope. I want to believe things will get better, that I'll make it out to the other end. I can't help…
