Listener question : when boundaries get challenged

Listener question:  

Do you have any comments that I could consider in terms of taking blame or feeling guilt for something, please? 

The position of self (which feels like me, inseparable, not something I am observing) is that I made choices to set boundaries in relationships, which in these instances meant prioritising a professional coaching relationship rather than a friendship. The result in the others is that they feel rejected and hurt. I feel responsible for their pain and I hate that I have hurt them or made them feel unworthy of friendship, to have made them feel not good enough. If I had continued in the (blurry) arena of being friends and coach, they would not be feeling that way. Therefore, their pain is my fault and I feel so guilty and horrible. Urgh......
