My first flight was when I was 21 years old around 8 years ago. Since then I've had more than 30 flights. All of them were normal, I never experienced anything too turbulent or threatening in any of them. None of my family members, relatives or friends have experienced even minor flight related trauma that I know about.
For the last 7 or 8 flights (roughly 3 years) I have noticed that I get extremely anxious before a flight. It sets in when I am on my way to the airport. I start feeling stomach cramps, anxiety, I had to focus to breathe, and my head starts spinning. I had to concentrate extremely hard just to get through security and reach the flight. In the flight I usually try to sleep and think happy thoughts. Otherwise my head starts hurting. It all goes away when the flight lands on the destination.
Today was the worst case of it all, I had to take an Uber for 30 minutes to reach the airport. The anxiety started setting in when I booked the Uber. On the way to the airport my head started hurting, I started feeling stomach cramps and the only way I could calm myself down was by thinking that in the worst case I will die a painless death if something happened during the flight.
When the Uber reached the airport, I was in full panic mode. I didn't want to get out of the Uber and just wanted to go home and sleep in my bed. Somehow after struggling for a couple of minutes I got out of the Uber and went forward. I had to use all my energy and strength to check in and get past the security check. After that I sat for half an hour and drank water to calm myself.
Still only half of my brain was working, once I got in the plane I listened to some music, which calmed me down a little bit more, but I was still too tired to do anything, so I just closed my eyes and tried to sleep with a sleep mask. I did sleep for a brief period of time but for most of the time my head was hurting and I felt energyless and powerless.
Once the plane made first contact with land at the destination everything was gone. I felt normal like I feel on normal days, I had energy, the head hurting stopped, I could even think and make decisions and it's been normal since.
I think I had a panic attack when I was exiting from the Uber. However I don't know what panic attacks feel like so I am not sure.
I don't know what to do or what is causing them. I really want these to go as in the future there will be a lot of travel by air for me.
