I broke dishes in the garage once. A whole box of dishes I was going to donate. Concrete floor. You get the picture....
It is freeing to just let it all out. I felt better, even having to clean up the mess. And no one was home at the time so it was just me and my anger.
Welcome to SR - this is a great place to vent, ask questions, get advice and hear others' stories. I use SR daily in conjunction with Al-Anon twice a week...has been very helpful in my own recovery from this mess I have found myself in.
