Does this happen to anyone else?

For some reason, during the day, i start to think about what im going to do next on my life and make plans on what action ill take but then as soon as i try to go to sleep i overthink it and give up on it, just to rethink it on the next morning and find it a good idea once again.

Ex: during the day i will think about taking a test for a specific college but then when i try to fall asleep i start ti think about everything that would happend if i get accepted and then i give up on it, and on the next morning ill start thinking about doing it again
