What could be the reason for my constant throat irritation?

Hi doctor,

I have been suffering with some irritation in my throat for the past one and a half year. I am just fed up nowadays. Also, the fear of cancer destroying me. After taking different types of antibiotics from different doctors, lastly, I took Loratadine and Dexit (Flupentixol + Melitracen) from a reputed ENT specialist. But, the problem remains the same. Moreover, withdrawal syndrome of Dexit makes me more anxious like shortness of breath, increased heartbeat, tiredness, restlessness, etc.

The nature of irritation differs each time. Sometime, I feel it as more worse. It is really very mysterious. I had tonsil pain for two or three times and then there is no pain or irritation. I had an endoscopy with my ENT doctor and it was normal. There is no trouble in swallowing, even I feel comfort. But after eating, I feel as if the food stuck in my throat and I am trying to finish it by constant swallowing. Sometimes, I feel as if the food loaded up to my throat.

During the start of the issue, there was no lump. But, after some five or six months, there were swollen lumps of lymphoid tissues seen. But, whenever I consult a doctor, I am getting the reply as no cancer and wait for it to resolve by itself. Please check the pictures of my throat. My doctor always used to say that there is no risk of cancer. Please check the pictures of my throat. I also had a panic attack just before some days. My sister also has tinnitus. I am not satisfied with my career and environment. Recently, I got married. I am a chronic smoker and recently stopped. Please help me.
