How can I manage the pressure I feel from the eyebrows that extends till my head?

Hello doctor,

I have been having a really strange problem for the past five months. I have been to the doctors and got some blood tests done with some CT scans as well and they told me that they cannot find anything wrong with me. So I am beginning to think that this may be a mental issue and I feel as though it is gradually getting worse. I have a painless tight pressure that starts from the top of my eyebrows and ends at the back of my head, then I start feeling as though I am not an actual person for a moment, I feel as though I am not real. I catch myself just staring at stuff and what worsens my issue is when I look at something, I feel as though I am not really looking at that specific thing. Like right now I am looking at my screen and typing but my brain just makes it feel as though I am not really doing any of that. I have also been very forgetful. It has gotten worse to a point where I cannot remember the things that I did past a minute. I do not even notice or realize half the things that I do anymore, nor can I remember half the things that I do and it just makes me really sad. This all started a day after I finished drinking a Four Loko, a bud light, and a coca-cola all in one night and I stayed up until 5 AM or so. Please help me, I feel as if I am going crazy and I am scared to die even though I feel it is already too late.
