Confidence

I've noticed something: When I become suddenly irrationally afraid of something I've been doing for months without a problem, like the war I had with the stairs a few months back,It is because I suddenly stmble upon a problem when accomplishing the task, and as a result, I lose confidence in myself. I've never been over flowing with confidence, I'm more of a fake it til you make it type girl. So when I suddenley start having some balance issues when climbing the stairs, my confidence falters and I start worse-case scenario-ing, which just makes me more afraid and more shaky and nervous when I'm trying to accomplish whaever it is that's scaring me. The other night I was in the process of not facing a common fear, going into the bathroom, now our bathroom that is upstairs is the one I use at night. The doorway is right at the top of the steps and I have to turn lrft to get into that now turning left is not my forte, so I always end up getting my arm  stuck on the door and because I get freaked out my  left leg muscles get spastic so I can't bend it and I end up fumbling around in the doorway terrified of losing my balance and falling down the stairs, so I turned around back to my bedroom, to put my leg brace back on, I always feel much more secure and stable with my brace on. But I dtopped myself, I said, "You're never going to get over this if you don't at least try, you don't want to have to put yor brace on everytime you go to the bathroom. So I did it, I faced my fear and got into the bathroom with no problem and I hav every night since. I always give myself a little patt on the back after I perform a perfect bsthroom entry and I give myself a little pep talk on my to the bathroom and I tslk myself through the procedure. Si I figue if I can keep believing in myself and facing my fears, there ain't notin' I can't do.
