I really feel for you. I'm a single parent to my 3 dc aged 10, 8 and 18 months. Like you, I work and they don't see their dad as he lives in another country. So all in all, it's completely exhausting!
I dream of having a lie in, or someone coming and offering to do DIY or tidy my garden etc. Dating isn't practical as I can't afford a regular babysitter, even if I found a date! So I fear I shall be alone at least until my dc are grown.
I try to make the best of everything, and work hard to make sure my dc gave a great life and don't miss out on experiences that their friends have, but sometimes I just want to sit down and relax rather than living life at 100 mph.
My 10 year old and I clash, so I empathise with how your feel towards your dd.
I so wish I could give you suggestions or solutions, but I haven't wirked them out yet!
Don't run away, it would be cold under a bridge, and thinking of your dd left at home alone would soon have you running back. She loves you most in the world, that's why she treats you badly sometimes, because she trusts you and knows you'll love her anyway. It's not right or easy, know.
Big hugs x
