Just that, really. I have a message written to my ex in my head halfwritten in my phone notes and my trigger finger is itching to send.
I shouldn't, should I? It's only been a week and I feel like I've fallen off a cliff and kept falling. Even though I had a couple of episodes of severe depression 10 and 15 years ago I'm a bit astonished to find myself ill again. I'm seeing a mental health crisis team at the moment. (Resourcing there is another issue...)
Realistically the only reply my addled brain could deal with at the moment is, "Oh, I've made a terrible error and should never have left you." And it's not going to be that, is it?
