i'm sorry you're going through this and hope you feel better soon. i strongly advise you see your primary care provider as soon as possible to diagnose what is going on. it could simply be that you're young and working a lot and don't have time to eat. or it could be a symptom of a larger condition that needs to be treated. unfortunately it's impossible to diagnose something like this from the internet. you need a physical exam and possibly some blood work to find out what's going on. you deserve to be treated if appropriate and live a full life. age 22 should be the prime of your life! i hope this helps.
as of lately i noticed a sudden weight lost(13lbs) i am always tired/sleeping even after sleeping a great amount. i am a petite 22 year old female. i never had such issues until recently. i sleep great amounts and yet i still feel very tired. especially when i do eat. i lost a total of 13lbs and i have no idea how. sometimes i do not even have an appetite. i also noticed a slight numb feeling on my right toe. at night i have trouble sleeping as well.
