Suddenly the chronic fatigue is fatiguing

I think I spent the last 2 weeks riding the high of having a new hyperfixation and now I'm coming down. I feel so exhausted like I can't do more than one thing every day. I'm supposed to be making a cosplay but after working for like 20 minutes all my energy fizzes out. I'm also really bad at it lmao. It's not like I have absolutely no experience but I'm certainly not great. I reaaaallllyyyy wanna finish it though because I spent so much on it and it's gonna be the coolest cosplay I've ever done (for now) and I can't wait to take it to a con and my therapist is excited to see it and I'm so close yet so far! I feel like once I'm in the cosplay I'll be energized again because it's from said new hyperfixation and cuz cosplay is the greatest escape from earthly troubles. I can't be in the cosplay til I finish making it tho :/. TMS might also be why I'm so tired all the time. I mean why do I have to go 5 days a week? That's like an entire work commitment except I just get zapped in the brain for half an hour (it's so painful). If the treatments end up not helping (they're for depression) then I will be so sad because this shit takes so much of my time and energy (and also cuz of depression ig lol). I think I still have like a month left of treatments uuuugggghhhhh but then I guess I'll be able to move on to the next part of life or whatever, probably getting a phlebotomy certification and becoming employed. Perks, I'll be able to afford making my next dream cosplays!
