 [ Symptoms ] as of lately i noticed a sudden weight lost13lbs i am always tiredsleeping 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 [ Disease ] i am sorry you are 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 are young and working a lot and do not have time to eat or it could be a symptom of a larger condition that needs to be treated unfortunately it is impossible to diagnose something like this from the internet you need a physical exam and possibly some blood work to find out what is 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
