I've posted before about the issues I had in my current job. I was only in it 3 months after being made redundant from a long-term job.
I struggled badly with imposter syndrome, daily my head was saying "I'm doing this wrong, I'll get found out here, I'm not good enough for this job" you get the idea, I had myself stressed out daily, granted the job rather the company wasn't the best but I had tortured myself, but the worst thing is when your head is saying that it almost becomes a self-fulfilling prophecy, you do end up making mistakes etc.
So managed to land a job with a family member, really don't want to cock that up or it goes back on them. How can I stop the imposter syndrome from kicking off again, its like I almost am trying too hard to impress or something
