Ok I know the title sounds a bit random but basically I have always been quite a reserved, anxious person. I'm confident in settings such as with close friends or family but not necessarily with people I don't know. My main issue is that I have very low self confidence and don't trust my own judgements at all. I think this stems from always wanting to please people/not upset people. If I feel like somebody is upset or annoyed at me for something it will massively play on my mind and it will be all I think about.
I know this can be a common thing but it's becoming a bit extreme. To the point that a year ago I decided to finally report my childhood sexual abuser, however after I did I spent the next few weeks obsessively worrying how it may affect them/if they would be upset, what if I caused them to harm themselves or something. Which I know is ridiculous.
So my issue now is that I am currently re training in a new career. I absolutely love it but it is a role where I will need self confidence and my lack of confidence in my own judgements are starting to affect my training. Is it possible at 30 for me to change? I've looked at books etc but I don't know if that would work for me as I've tried self help books before and didn't get much from them. I've looked at hypnotherapy, counselling etc but wanted to see if anyone had any other suggestions or just tell me I'm being silly and it's too late to change!
