Celiac? Candida? Allergies?

I am looking for some possible feedback on my symptoms. About 9 years ago, when I moved to a new city, I started experiencing Blepharitis or something of the sort. Before I moved I was an A student, and once I arrived in the new city my grades began to drop. I often found myself feeling the need to skip school, especially my morning classes because I would feel stomach aches, some days worse than others. Recently I have noticed the pain goes away somewhat once I make a bowel movement, but I have also been experiencing chest pains on the left/middle of my chest. It is an aching feeling but gets worse I believe when my body fills up with air, this leads me to believe it might be my lungs. Sometimes I feel the ache on my right side but not often. The pain seems to subside sometimes after a good bowel movement or when I burp, which often are very deep rumbly burps that feel like they come from the bottom of my lungs. I seem to have sinus problems so I breath through my mouth a lot, and sometimes when I try to fall asleep I am pulled awake I believe because my body gets confused whether it wants to breathe through my nose or my mouth. I also have had tonsil stones for as long as I can remember, but got a lot worse once I hit my teens. I once took an antibiotic for it and never finished taking them. My bowel movements are usually within 10 minutes of eating and usually have 2 per meal. They are usually very loose and gassy, and leave a burning sensation sometimes, as well as blood on the toilet paper (very little). I ate A LOT of sour key candy a few days ago and my throat seems to have disliked it, I didnt get tonsil stones but a bubble of what looks like puss formed about half an inch closer to my mouth than my tonsils. I notice sometimes when I am nervous I have to make a bowel movement, but sometimes I become constipated at that point. I have tried probiotics, they help with the time in between but the end result is still a gassy loose bowel movement. My movements arent always loose but yesterday morning on an empty stomach I drank pickle juice and it was ready to come out two minutes later. Please let me know what you think!
