Oh yeah, definitely, had a similar reaction when I first started it. Most of it was geared towards my Dad who was very strict on me my whole life. I had A LOT of resentment towards him which came out during the confidence sub. It's nice because since I stopped using it (months ago) I no longer allow his negativity to affect me and my self-esteem, but he's also been more respectful towards me. This happens for about 2-3 weeks, then you start to gain confidence. You gotta release that baggage, look at it as a learning experience. You're now beginning to understand why you lacked confidence in the first place. I'm sure resistance in itself can also manifest in anger. It'll all go away very soon
