Terrible chronic fatigue at 20yrs old?

Katherine • New to this 😅

I’ve had the WORST fatigue of my life for the past couple of months. It gets worse around the time of my period/during pms. I’ve noticed some weird hormonal changes too like shorter periods, worse acne/cysts, multiple canker sores. But the fatigue is really killing me, every night around the same time i get so tired I have to take a nap. Has this happened to anyone else, maybe i’m low on nutrients of some sort. I know reasonably I should go to my doctor and get a blood test for my hormones (i hate needles lol) but I was curious to know other experiences! Or some recommendations on vitamins to try. Thanks so much :)
