Tough time

Having a really tough time at the moment so there's no real point to this post but I just need to unload. Since my LO turned 1 her sleep has become horrendous, she's unbelievably clingy towards me (ordinarily I'd soak this up) but I can't catch a break. She's refusing her Dad, has almighty meltdowns/tantrums which I understand are developmental and I'm trying to remind myself this but I am so exhausted from 3.5hours of sleep each night for the last 4 days that my patience is wearing thin. I just feel like nothing I'm doing for her is good enough, I'm struggling to be the happy Mum with lots of activities because I have zero left in the tank. She now has croup and an ear infection which yes I know is probably adding to all the above, but I just need a break. My partner tries his best but he struggles withe the rejection so he backs off but he does help but she just escalates further so I end up having to fix it. We have no extended family support so it just falls on us. We have my partners Mum and Dad but they have never once offered to help, they like to come see her weekly but don't offer to give us a break, my partner and I have not had any time for us in a year. Anyway I don't know what I'm saying really, just needed to offload. Thanks if you have read
