My first semester haven’t even started yet and I already feel like I have imposter syndrome

I feel like I’m overthinking a lot of stuff like if i took the right program and already feel like i want to switch, or if it was worth it to go to another city and live in res and be away from my family, then to go to a nearby uni and commute.

Idk if it just first year anxiety or something but I wasn’t feeling this way before but now I am.
