Is this a form of anxiety? What is this?

I feel like I’m constantly questioning my own decisions. I feel like when I’m making a decision that I need someone there to give me their input. Not all the time, but a whole lot of the time.

It’s like I don’t trust my own judgement. Like I feel I am too dumb to make the right decision.

Why am I feeling this way? I just started feeling this way this year. How can I help it?
