So many negative thoughts

Dear Brooke,

I see that I indulge in confusion in most areas of my life and there are many thoughts that cause it. Some of the worst are:
I don’t know what to do.
Is this the right decision?
I’m afraid of making a mistake.
I’ve made poor decisions in the past.
I’m afraid of depression and not being able to cope if things go badly.
Life is short and I can’t afford to take the wrong path.
It might take years to correct, I’ll never get this time back.
Nothing I do works out.
I’m not as strong/healthy as other people so I need to be more careful in my choices.
I’ve been unlucky.

What a terrible list! Where do I start?
