Right then OP. I know it doesn't feel like it but you are doing a FAB job. Seriously, you're on your own with no support. I don't think anyone would cope under the circumstances.
FWIW I hated the baby days so much. The constant crying and screaming. A baby who wasn't content anywhere, or with anything. It was just a constant state of misery.
I had plenty of days where I bitterly regretted having a child. I felt shit, useless, guilty and just totally lost. I fantasised about killing myself, putting him up for adoption, running away, throwing him down the stairs.....all sorts of crazy thoughts.
I pushed myself harder than I ever thought possible to build a good relationship with him. My god, it wasn't easy at times but my son is now 5 yrs old and the most awesome human being I have the pleasure of knowing.
When you're stuck in these dark times it is very hard to appreciate that it's really just a moment in time. You are in the trenches at the moment and it's fucking hard. But, being a parent you're in a constantly evolving state. You will look back on this in a year, two years, five years and know what I mean.
But right now, I hope that you can take each day as it comes. Every day that passes your baby is getting a little older until one day, you will blink and they'll be at school.
Time is standing still right now, but I promise - it won't always be this way.
