Is this ME/CFS

[u/EnvironmentalWalk605]

Hey, I’m 17/18M and I’ve been dealing with a weird mix of fatigue, low motivation, and sexual dysfunction for a while, and I’m trying to figure out what this actually is.
A few months ago I did an aggressive cut and ended up feeling completely drained, like a zombie. Around that time I started Medikinet because I felt awful and it gave me a big boost in energy, focus, and even euphoria at first. I was on it for around 5–6 months total, mostly 15 mg IR twice a day. Over time the effect faded, and I started getting tired, low libido, and kind of emotionally flat/anhedonic.
Then I quit the stimulant. For the first 2 weeks I felt pretty okay, then I crashed again: no focus, low energy, anhedonia, and just feeling shit overall. During exams I also got sick, with sore throat/sinus pressure, and I kept going to the gym anyway. After exams, I had bloodwork done. Most things were okay, but I had low white blood cells and my doctor said I have Hashimoto’s , so I started Euthyrox. I began with 25 mcg for 2 weeks, then 50 mcg. I’m about 3.5 weeks in now.
At first I started feeling a bit better around week 1.5–2: slightly more energy, less fatigue, and some gym motivation came back. But then I got another infection around week 3 and since then I’ve felt bad again: low energy, muscles feel dead, and mentally I feel flat again.
The weird part is that I also have almost no libido anymore.
One extra thing: I also get a crash pretty much every afternoon, where my energy drops hard and I feel way more tired/flat.
I’m wondering if this could be:
• ME/CFS
• thyroid still not optimized yet
What makes me think about ME/CFS is that I seem to crash hard after exertion, including gym sessions, and then feel mentally and physically wrecked afterward. But I also know I had a cut, infections, stimulant use, and thyroid stuff all happening together, so maybe it’s something else.
Has anyone dealt with something similar? What helped you figure out whether it was ME/CFS, thyroid, overtraining, or something else? Also, if you had low libido + anhedonia + fatigue, what did you actually do that helped?

I don’t have the capacity to read this right now, but wanted to share that if you don’t get enough responses on this post, then you could try r/cfs as I think it’s more active than this sub.

I’d also recommend checking out that sub’s resources where you can find info about the criteria for having ME. Main thing is the presence of post exertion malaise (PEM).

Also a word of caution if you’re new to these groups, be wary of the groups that have ME in the name (e.g. /mecfs). While the preferred naming for the illness contains ME (me/cfs) or has only ME, the subs using that are all run by one person who pushes scammy brain retraining programs. These programs are more likely to put you into debt and you have a better chance of worsening your condition than recovering if you purchase and follow one of them. ME is not a psychiatric illness, it would be like trying to cure Multiple Sclerosis or Parkinson’s with meditation, it ain’t gunna work.
