Yes, things take time. You are probably noticing and challenging faster and better now and the negative feelings probably last for a shorter period of time, etc. Accept that you feel and act like a "mortified, angsty teenager". There is nothing wrong with feeling one way rather than another, it may not be pleasant but if you fall in a mud puddle, you are going to feel muddy? It's okay! The interesting part is to get to a place where you can shower as soon as possible and remember the whole experience so you maybe don't fall into mud puddles as often because you aren't paying attention or something? Figure out why something happens, what triggers it and accept your feelings and then act in a way you like, that helps you. Right now you are challenging your thoughts and I predict in the future you will probably be able to learn how to not fall into mud puddles so often?

I love David Reynolds books, InTheShadows; there was a time I found them very helpful.
