L-Carnitine (not ALCAR) - Day 1

Today I hit the end of my rope. I've had fatigue that hits me hard every day around 11AM. Generally everything that is supposed to give me energy gives me horrible anxiety. Even D-Ribose. Caffeine is like playing Russian Roulette and always makes me crash. B12 lowers my iron (I take a very small sublingual dose now). ALCAR made me anxious. The symptoms get so bad that I dissociate. I can go from functional to barely human very quickly. I get tired and lethargic and it's difficult to stand. Today I had off. The wife and I went out to an arcade. I tried my best to keep my composure and enjoy myself. We rarely go out due to having kids. But in reality I was so lethargic that standing there playing basketball or a game I felt so woozy. I got home and went to lay down, which I hated to do since I wanted to get some stuff done. I laid there depressed about it all. Is this the rest of my life? I've tried so many medications and supplements... I had bought L-Carnitine awhile back but never tried it due to being scared of more anxiety. I was also adjusting medications for mental health. I decided "screw it, I'm home today" and took one capsule of Nutricost L-Carnitine (500mg) and went to lay down. About 45ish minutes later I woke up to a surge of energy. Not bad, but definitely was a little overwhelming. I went back to sleep but kept waking up. That was about 3 hours ago and I honestly feel... Good. The energy makes me feel normal, not over the top anxious. My head feels clearer. I'm not woozy. My dissociation is very diminished. I'm hoping that this continues, but I am very skeptical given my past. COQ10 did something similar and fizzled out after a few days.
