Please help!

Ok,I have been sick for over 7 months with mostly GI problems.My main concern is weight loss.I eat even more now then I did before and continue to lose weight.I was 125 in August and am now 103.I am even drinking weight gain shakes.I have had colonoscopy/endoscopy and everything is fine except mild gastritis and small hital hernia.I have also had capsule endoscopy that showed no abnormalities.My thyroid is fine,and I am not diabetic.Adrenal gland is also working properly.I am at my witts end,I am so afraid I am going to wilt away,I have never been so skinny.Does anyone have any ideas what may be causing this??
