From major life ones to what to order in a restaurant.

"I'll have the vegetarian." "Are you sure? We have some lovely meat." "Okay I'll have that."

Right now I can't decide between going on holiday or staying where I live and training for a marathon.

Any time someone mentions a holiday I get really jealous and anytime I see someone running I'm like "I should be running."

Worse I change my mind a few times to make sure everything gets fucked up and I don't get the benefit of either choice.

I think what might help is writing down the choice first and also sticking out the decision. My mind isn't occupied enough/is fatigued so it comes up with a million reasons for and against which build until I can't take the anxiety and change my mind.

It's making my life hell.
