Neck / throat lumps

Hey hope everyone's well. Just wanting a bit of advice. I've been back and forth to fb since 14/04/21 with sore throat and various other issues. On 18 may I noticed on my right tonsil at the bottom there was some swelling (for me it looks like a tumour) went to walk in centre on the 19th may and was told not to worry it's just swelling. Then later that night I felt a lymph in my neck (same side and swollen tonsil) but thought I'll leave both for 3 weeks and try not to worry (have health anxiety) so saw gp who felt neck and checked throat and said not to worry I think it's just pharyngitis and said to leave it and he will call back in 3 weeks. 3 weeks later it's still there so booked me in for another face to face for Friday just gone. Saw him and said due to symptoms and time ongoing best to get checked out and I'm booked to see ENT tomorrow morning. Said again he doesn't think it's a concern and not to worry but i am worrying and and can't stop overthinking that I'm gonna get cancer and die. I've had ear ach for a while. Build up of pressure in my head where it feels like it's going to explode. Also my bruising has got worse this year (bruise easily) but now getting bigger and worse bruising so think could be affected. Also my glands under my chin (but in left side) felt swollen since April and a slight pain there 
 

sorry for the long post. But can anyone offer any advice what to expect with Tomorrow's appt and has anyone had similar symptoms and what was the diagnosis?
