Recently started a new job, I'm a trainee so I've made some mistakes. When I mess up, I say sorry and apologise a lot. My manager says to be more confident, it's a sales job too so this is really important. I just hate myself when I mess up, I don't think I'm very emotionally mature because I just feel shame and it doesn't help me.

I had to make a snap decision at one point with the manager sat next to me, I froze and wasn't saying anything, she told me to go with my gut, but I didn't even know what it would be, everything I say and do is thought out so much, I don't know how to make those snap impulse decisions under pressure and I hate myself for it.
