Oh that is such a lot to be carrying by yourself, I know you said your friends stopped asking or offering help (mine have too) but would there be one of them you could approach for a cuppa and a natter.?or even someone that could mind your little one for just a while so you could have some time out and maybe a nap by yourself?
You are doing an amazing job being a strong mummy and daddy to your daughter, please know that and I am sure your dad is around you every day and is so very proud of your courage and determination.
I am sorry you are having to also deal with your unreasonable ex. Divorce is so hard and heartbreaking, more so when there's a little one involved. Sometimes men can act like spoilt toddlers themselves!
I thank you for keep talking and sharing, I hope it's helping? I wish I could help more, but I am listening and am sending you virtual hugs and strength ♥
