I've recently started therapy (four sessions so far), and I really struggle with self-criticism and self-worth in that I question if I should take up the therapist's time when there are people out there with bigger problems than me. People lose their spouses to suicide and their kids in car accidents, and I make enough money to spend it on complaining about not being happy enough for 45 minutes a week.
I also question my therapist's motives, since they obviously want to sell this service and would probably put up with any of my nonsense for a quick buck, while shaking their head at how minor my issues are compared to their other clients. But it feels nice to be able to talk uninterrupted for a whole session, without a regular conversation's context switching back and forth, so there's that.
