Do I need to see a psychologist?

Okay so I tend to think a lot, like I would drive like for an hour and just think of scenarios. Today I did it 3 times😬😭😭😭😭 so that's 3 hours and it's probably a little more😭😭😭😭 
Also, a lot of times --people would just look at me and see me smiling and ask why. That's because of something I'm imagining or thinking. ---what do I do?😭 I also even think of people from years ago and remmber stuff n even have back a little crush for them or so again.... It's so crazy, I don't like it!😭
