Hot mess + life coach

I’m struggling because I’m a life coach and I always feel like such an emotional mess. I need some thoughts to help me think more positively:
I love personal growth
Coaching is so helpful
Because I struggle, I can help others

The thing is, when I tell people I’m a life coach, I feel like they are judging me like- what gives you the right to be a life coach. Are life coaches supposed to have their shit together?
Especially close friends that I often vent to..
I’m not sure if I have unrealistic expectations of myself?
