Am I overthinking this situation about a girl (friendship question)?

As humans, we sometimes think a lot about a subject and then begin to think longer and harder and sometimes what we are thinking about morphs and we begin to think of maybe the worst case scenario or many what ifs. The important thing to do if we are struggling with a relationship is to communicate and talk it out as that's how we understand each other best. Connecting with a listener is a great place to start to understand more of what you are thinking in order to start coming up with a plan on how to approach your situation
