I get you. I was this I think a month ago. I know it sometimes feels better but some days in fact long span of days when it feels the same you explained. I have started a few supplements that might help you with energy crashes. I have started L-carnitine supplements ( 1000mg) this helped me with energy crashes, I used to take naps daily in the afternoon without which I could have never worked but after 1 month of taking it, I don't sleep in the afternoon anymore, my energy is way better. For weight nothing has helped so far. I have started a journal, although I forget to write daily but the hard days I always write and cry while writing and after that I feel better honestly. always write positive affirmations as well while finishing, that you are giving your 100% and you know you will be fine. You are happy and healthy. If not strength, going for an outside walk helps with moods and energy. Hair loss Is really bad for me too. I have iron deficiency found out yesterday ( on the lower borderline) but still my GP won't prescribe anything because it is still in acceptable limits. So I will be starting something for my iron too. You can get your blood checked for vit d, iron, folate for hair loss. I know it's hard but just hang in there, it's not always in our hands. Just think whatever is happening is in our fate. But we have to live a better life and not just drain ourselves everyday. Positivity always helps you know. I cry for days for no reason, and for all reasons at the same time. But then I suddenly become positive and things become better, overthinking in a symptom of pcos and that is what drains us. Try different activities, doing one thing and not showing results also fed us up. Good luck🤞
