I want to be me again

I got bloods done a few days ago because I've been fatigued ALL the time for the past few months (it got really bad in the past 2/3 weeks). I'm in my early 20s and I was shocked to find out I have hypothyroidism. I don't know much about it but everyday I have to google "is 'XYZ' a symptom of hypothyroidism"...and it always turns out to be the case.

I have to get another blood test in 2 weeks (the Dr said my case is slightly complex due to other meds I'm on so she can't prescribe anything right away). But I am SICK of feeling this way.

I feel like I don't know who I am. I get random short bursts of energy (20-30 mins) throughout the day but I never know what's going to 'trigger' them, followed by being completely bed bound. I speak so monotone most of the time now and I don't find things funny. It's so sad because I love laughing but I just don't have the energy to laugh. It's as though the real me is trapped behind a glass.

It's awful that I have to wait so long because there's nothing I want more than to be me again :(
