I wasn't strong enough or confident enough in myself at the time to know I'd be ok. My girls will be ok too.
Well, maybe that's what the last few months were about then. Doesn't sound like it was a waste of time then. So don't be worrying 'oh if only I left earlier' - if you had, you might not have made the personal gains that you did. The road to inner strength, confidence and self-acceptance is always bumpy and can hurt; I don't think it's supposed to be smooth.
I cannot complain for not receiving from others, that which I've never asked them for.
