I usually weigh 89 and now I weigh 79. I have been eating a lot but not a crazy amount more then usual, and I realized I lost 8 pounds. I mean I have unprotected with my fiance and I feel like crap lately, I feel sick and like I look pale and like crap. What is going on?

it sounds like you need to go to the doctor... asap

Hi it would've been easier if you mentioned your age to determine the situation more thoroughly, but losing weight drastically at this rate is not healthy, you should consult your doctor or physician for better assistance but all these symptoms may have been routing to diabetes ,, you should get a blood test to examine the real cause,,,
P.S. can i get my 10 points
And pardon me for my advanced english if it was hard for you to undersatnd
