help me out. ! Never felt well

I've been roaming around each and every corner of the medical resources for years as i am member of many group forums and internet platforms i am much of a reader though i just read dont make posts myself anyway what i believe to have caused myself to get all the discomfort for years is allergy and gastrointestinal trouble and these two made me panicky and caused me to be anxious on a daily basis. I.to never had a good clean breathe for so long i feel like I'm always out of breathe my eyes and nose burn&itch 24/7 i get dizzy and sneeze a lot like 24/7 and i have asthma too my when i eat my stomach go crazy and stool looks very very awful makes me sick .

no I've never been to allergist cause i never even assumed that this little devil can do so much harm to someone i always wondered all my life why i always feel discomfort why i am easily out of breathe why i feel so bad if i smoke a cigarette when my friends smoke one after another and they are totally ok. I have had asthma all my life . I get severe attack once or twice in a year. Anyway i used to cope up and i just assumed its just meant for me until .2014 when i came down with full blown panic attack one day and my days were ruined i was in Hell all the year round . Loads of symptom and no possible answers i thought i got something like cancer or something serious and i was about to die i never thought of allergy though i had many tests done and the tests concluded the possibility of having something serious . I never knew what was causing all this. I used to have panic attacks last year. This year i have too from time to time but i dont freak out that much as before. Some of my symptoms r - the worst thing is the trouble breathe i cant breathe my nose is always blocked its been blocked for over 5years or longer sometimes its runny sometimes its not but blocked the time. Partially blocked sometimes. Redness of eyes from mild to severe. Eyes burn 24/7. The second most affected part is gastrointestinal part. I feel bad after i eat to some extent. I sneeze or burp a lot i always have loose stool sometimes diarrhea too . My stomach burns and hurts from time to time . The worst thing is it sometimes doesnt let me breathe. I cant breathe sometimes after i eat my tummy becomes bloated and feels like I'm breathing through stomach. It happens pretty often. My bladder hurts too sometimes i developed mild cystitis. I also have some numbness tingling dizziness heat intolerance sweating excessively muscle spasm panic and anxiety attack.
