Hi Daisy. Glad you are feing calmer. Not so glad to hear you don't feel well. I hope it has passed now. If not, stay warm and rest!!
I am so sorry to hear about your troubles with your son. But don't apologise for ranting here!! This is the perfect place! Come and share with us whatever is going on. We are your support network. Because if you don't share that resentment may sit with you and fester and us alcoholics cannot afford to have resentments! They can take us back to a drink and for us to drink is to die.! So share away lol.
I think it boils down to the whole powerless over people places and things. We can't control how others act, live, behave or react. Only ourselves. We need to decide what we are willing to tolerate, how we deal with others and situations and what boundaries we can put into place to protect ourselves and it sounds like you have that insight which is amazing! And again, I echo others, thank God your grandson has you.
Really hope you are feeling better today.
