You've seen doctors and a specialist, so it's hard to know what to tell you. It sounds like a mild migraine condition, but it could also be coming from that painful neck. But a lot of what you are describing sounds like a mental problem. Having forehead pressure would be annoying, and not knowing why could cause nervousness, but you're describing a pretty strong emotional reaction here and I would investigate mental problems such as depression and anxiety because you sure seem to be describing that. There are conditions that can cause mental problems, such as thyroid problems, blood sugar problems, nutritional deficiencies, etc, so a thorough work up with a doctor might be called for. But head pressure is a definite symptom of anxiety, and you're describing, again, a pretty significant mental disorder. It doesn't seem forehead pressure would cause such an extreme mental reaction, so again, I'd look into that. Peace.
