"Ulcer" OR "Allergy"? "Allergy attack" OR "Panic attack"?

Dear Sir/Madam,
I'm 21 years old male
Height - 5'9
Weight - 50KG (Approx.)
Occasional smoker

I have been on Allopethic medicines for the past 2 years (almost) for some really disturbing problems but my health condition is continuously deteriorating instead of the problems getting completely cured. I am mentioning my problems below and hoping to find a permanent cure for them.

I get this burning feeling in my throat, chest and stomach whenever i eat anything which has the smallest amount of spice and/or oil. (i've provided a few pics of my throat)
My skin of armpits, pelvis and sculp itches too much most of the time and it makes the skin red and i'm experiencing too much hair-fall.
My stool is not normal and very inconsistent. Most of the times its yellow and type6 of the Bristol Stool Chart and sometimes contains slippery substance.
I sweat a lot, esp. palm of my hands and foot and the armpits.
My stamina is really low and i get tired even if i walk for only 10-15mins.
I have a sinus prob since i was around 12 years old.
My nose is blocked/heavy most of the times esp. the left part. I am too sensitive to dust and smoke. They give me instant runny nose, itchy throat and eyes, headache.
I also have migraine problem. Cant tolerate too much noise and chaos. Makes me dizzy.
I dont sleep well most of the time. It takes way too long to fall asleep. Also it breaks after every 2-3hrs most of the time. And i feel sick the whole day when i dont get a good night constant sleep. I loose my appetite, feel dizzy, feel like throwing up even when i smell food.
Sometimes I experience numb feeling all over my body and sweat a lot at the same time. Like panic attacks. I'm not sure if these are panic attacks or allergy attacks.
I dont like too much of any flavor (e.g. sweet, spice). But because of my burning problem inside my throat, chest and stomach i always have to take food without a little bit of spice and it makes me feel like throwing up most of the time.
A good night sleep helps most of the time. When i sleep well the problems are less effective.

The first time i went to my doc. for these prob he gave me some tests (few blood tests, urine test, and x-ray) and reading the report he said there's nothing serious while ensuring that the kidneys are fine too and said its mainly allergy. But he gave me anti-depressant (mirtazapine) along with a few other meds. Those helped me sleep well, brought my appetite back and i was almost fine for few months. But after the meds were done i was back to my problems. I have also had amitriptyline (anti-depressant) for few months later but i dint complete the dosage because of the side-effects. They always made me feel weak, sleepy, lazy, gave me blurry vision, slower thinking. So i had to stop. Now i'm on Propanolol (10mg) on a daily basis (2x a day) and Clonazepam (only when i have sleeping problem, which is most of the time).
Currently i have a flu from cold (cough, runny nose, headache, fever) so i'm having an antibiotic with paracetamol and a cough syrup along with the above two i mentioned.

Anyway, i badly need cure for the burning in my throat, chest and stomach since i cant eat which is making lose my appetite and making me weaker day by day. And i'm not sure if its allergy or ulcer.
Also need cure for the sudden numbness. It gives me real scare and gets my heartbeat real fast and i feel like i'm having a heart attack.

I've provided almost everything about my health that might help you understand my problem and provide me with some effective cures.

Thank you.
