Autoimmune Disease?

Hey first post on any kind of website like this but thought i'd give it ago as everyone i know is pretty fed up of me talking about my problems! So how it started, around 6 months ago when i was 19 (now 20) i was just my usual healthy self until a got violently sick one day, thought nothing much of it until i started getting pain downstairs which went on for a month or two, now here is where the real problems started.

I started developing stomach and back pain pretty severe with a temperature etc, doctors thought it may be gastroenteritis gave me meds didnt help, then they treated me for a UTI and gave me meds, settled down, i had lost my appetite but i managed to gain it back, along with the stomach problems i started to get dry, irritated eyes, now i have been told only recently i have dry eyes and blepharitis, and around 2 months ago i started to get alot of burning back, shoulder, neck pain, muscle ache, fatigue, sore glands, lymph nodes, headaches, slight tremors, dizzyness you name it, the dry eyes are still there pretty bad but the others have eased slightly.

I was a avid footballer and havent been able to play in 6 months. I went for an endoscopy 3 weeks ago and i have been diagnosed with duodentis and gastritis, not caused by H Pylori, still waiting on my biopsies back they took but it's not really looking good for me. They have tested my blood for so much, like lupus, thyroid problems, deficiencies and can't find anything, they call me the medical mystery. I can't eat well at all the last few weeks, anything spicy, greasy, or acidic drinks burn my stomach, i've lost around 10lbs in the last 6 months and i'm only 9st 4lbs which is pretty skinny. Personally I am concerned about an autoimmune disease, hoping for celiac but i fear it could be worse. 

People say it's probably caused by me being anxious but i know my body and i've tried to push on as much as normal but some things i just cant do anymore, so if anyone could offer advice that would be great smile

Btw sorry if you feel i have posted this in the wrong forum, but alot of my symptoms in my opinion do match to autoimmune diseases and to MS, for example for along time i had chest pains, which i know could me an MS hug. Muscle aches, fatigue etc, but the most worrying for me are the burning pains in my back and shoulders, that shot down my spine, those symptoms have eased off a bit now, which makes me even more concerned that it could be MS, Like i said i have problems with my eyes but my right eyes vision is slightly out of focus to compared to the left which i know is also common. However i don't have any balance problems or cognitive problems just mostly pain. Plus a doctor did mention booking me in for a potential brain scan as he said as rare as it is, I do fall in the age rage of MS, so just a bit more info for you all there on why i think it may be an autoimmune disease!
