unhealthy(weight and appearance)
I am a 19 year old male currently attending college at a state university. I am 6'3'' and I weigh 155 pounds. When I started college I weighed around 165 and I was looking to gain around 20 pounds but nothing I do has worked. I also look very pale and people often ask me if I am sick. I get 14 meals a week at a buffet dining center that is 30 seconds from where I live and I also work there so I get another free meal 6 days a week. I no longer regularly exercise, but I walk around my extremely large campus for well over an hour each day going to and from classes. No doctor has ever said anything about my low weight even when I bring up my concern that I weigh 10 pounds less than I did 6 months ago. Is this healthy? If not what can I do?
