Migraine Diagnosis and help :( Please

(please bare with me as English is not my first language, thanks)
Hi, I am 25 years old male. For the past 6-8 months my life has been turned upside down. I don't know what do to and where to go. I've lost all hope. So it all started back in March. I had some previous issues with depression and anxiety but not anything remotely close to a migraine. It didn't happen all of a sudden tho.
so, I feel like pinching sensation at the top of my skull but slightly to the right side. Its not pain per se but there's a continuous pressure (for the lack of better word) 24/7. Its like I could feel one of vessels in my head popping and swelling. Probably feels like inflammation or constriction but no drug whatsoever has been effective as of now. And its just there no matter what I do but gets increased by chewing tobacco or when I become increasingly conscious of it. My eating and sleeping has been good. But I feel it difficult to concentrate and recall things at times. There's occasional neck stiffness and crackling sound at the base of neck.
Doctors are as clueless as any other person. I dont know what it is. Its just eating me alive. Sometimes it feels like a nail has been placed in my skull. its been terrible. I have lost all hope and I cant imagine living like this all my life. there's no escape to this misery. I have lost a portion of myself.I dont know who I am anymore. Please help me please 🙁((
