I'm currently an intern at a large facility, and the work I do is very specific and requires a lot of small steps that need to be done correctly, or else the entire process gets messed up. 

Because of my anxiety and depression, I feel like it's impacted my ability to pick up new things. I'm so unsure of everything I do that I always have to ask my supervisor for confirmation. I feel like I'm so slow at everything and keep making mistakes. I made a mistake today that could've affected the end product if my supervisor didn't catch it.

 Does anyone else struggle with doing new things and actually retaining how to do it? It feels like every day I wake up and go into work, I forget everything I learned the previous day.
