I had a shitty job interview today

I had a shitty job interview today Not gonna bother you with a large paragraph. Basically: fear of stuttering took control over me and I was shy and short in my answers. I now feel like crap because I should have presented myself more. I always realise afterwards that I should have talked more but I genuinely lose control over myself during an interview, I'm always on 'automatic pilot' which means I just answer the questions quickly. There is no spontaneity from me when I'm on automatic pilot.
