I'm one of the angriest people I know

but I don't let that stop me doing good things too.
It's about awareness I feel. if you know there are things to improve, then you are empowered to do something about it. At least you recognise you're not being very 'reiki' so you can choose to change that

As other's have said; don't beat yourself up; you're giving yourself a wonderful gift - the ability to learn forgiveness first hand

Also, when I'm doing reiki it brings me out of my anger, so maybe there is learning in that too...........
I don't know what you 'issue' is, but the priniciple is the same
