Are these migraines? Has anybody had ones like this? Any hints on how to deal with them?

So, I've never had a migraine in my life until about three months ago (I'm 23 now).

The first time it came, I was driving and it literally felt like someone hit me in the head except without the pain. I actually swerved on the road, because my body physically fell to my right side and I regained control of the car. I was fine for a few seconds afterwards and then my eyes couldn't focus on anything.

I got really worried and pulled off into a parking lot where I laid down and took a nap, because it was too dangerous for me to drive. No light sensitivity, no pain... Just my vision was not working and part of my face got a little numb. I checked my pupils and they were both constricted for whatever reason, but no signs of stroke.

I managed to make it back home and the nausea I had gained went away in one night, but the vision issue persisted for roughly 4 days before subsiding. Then I fell depressed for about 2 days, which is 100% unusual for me. I love life, I love living, and I'm practically never down. I had no motivation and no joy in my heart for those two days and it drove me insane.

The next time it came was about a month later, and again with no headache, minimal nausea, and no light sensitivity. So rather than not being able to focus on anything, a weird squiggly snake like object appeared in my vision in my right eye only and was flashing colors. It wouldn't go away for several hours so I went to sleep early and woke up and it was gone.

The third time it happened, I managed to deter myself from falling into it. It felt like I was losing control of my vision like the first time. I wasn't driving thankfully this time, but I was in a car and there was a weird streak on the windshield that I couldn't pull my eyes away from and then I felt my eyes drifting on their own and I managed to pull myself out of it. There was no further incidences with this particular episode.

I haven't had a fourth since then, but I recently have started to feel... very unlike me. I feel like I'm responding to life through the logic of what I know I would respond to it with.... Like I know I would be upset by certain scenarios, so I knee jerk act upset, but I don't feel upset. I know that I love looking at the beautiful scenery and just relishing in it, but I find no comfort in it. I know it's beautiful and that I'm supposed to find it beautiful so I look at it... but I just don't feel it.

I can't help, but feel like I should attribute this slump of lack of emotion to these "migraines."

So now my questions are as the subject says. Are these migraines? Has anyone had ones like these? Any hints on how to deal with them?

What should I do?

Thank you! I will try and make an appointment. I work seven days a week, weekends, and holidays, so it's hard to find a time. But I will definitely contact one and see what's going on :) Thanks!
