last year at the beginning of summer i decided to do a weight cut and i maintained a low weight for a very long time until i eventually got tired of feeling like crap and decided to bulk back up but after wards a lot of the weakness/lack of libido/depression i felt while doing it continued on
so i got some blood work done the check if i was healthy and all the work came back great (even t -levels where good) but i Still felt this lack of libido while feeling void of any happiness sadness and aggression. so what other factors could be at play to cause me to feel this way?
i suffered depression as well as struggles to maintain a healthy weight i would be 10-20kg under weight or id binge and get slightly chubby (not big enough to be overweight or noticably chubby to anyone but i felt big)
i had blood work that tested for everything like yours i was clear of any problems. i fear you may have triggered clinical depression which is manageable if you seek help for such problem. there may no longer be a calorific cause and it may now be dealing with leveling out the chemicals you imbalanced in your brain by maintaining a low weight.
for me personally i tried anti depressants but for me after 2 years of trail and error i am yet to find one that works. i decided along with my Dr i would come off them (gradually) and do a lot of self help: daily walks alone or in company, working on my sleep hygiene (sounds bizare but its a thing and its worked wonders for my wondering mind at night), going to the gym rather then controlling weight loss/gain with my food, mindfulness and opening up about the way i feel or dont but would like to to those i love and trust most. i have really taken time to work on myself and im now able to manage work, doing a law degree, looking after my horses and having a wonderfully healthy relationship with my partner and myself.
its been a long process but it has really paid off for me. not many seem to understand the long term effects off a low calorie diet or a low weight. its very wise to have connected the two and its brilliant you are actively seeking advice. WELL DONE
