Any other Aquarius gets overwhelmed and overthink when someone you like cuts you off?

Depends, if I was cut off for stupid ass shit, then no. I am sad for a bit then move on with my life.

If its been a long time investment by both sides, then yes I analyze and try to sort out my part in the demise of the friendship/ won't stop thinking about it. I will even attempt to reach out to try to see if it can be worked on/fixed. If the other person still 1. doesn't own up to their part in shit and 2. is unwilling to continue being friends, I walk away.

I will never force a friendship, either we are or we aren't, period.
