Breakdown

I am a first time mum to my 10 month old baby girl. We moved 2 weeks before Christmas to a more permanent residence. I don't feel like it's a home though. It's a new build so we're in the defect period meaning we cannot pain or put nails or anything into or on the walls including painting them. It's like our furniture is in some small warehouse. I hate it and don't know what I can do about till we're out of the defect period. I'm currently mid breakdown. I couldn't resettle my little girl and it made me feel like a failure. My partner (her dad) took over from me after I had endured about 20 mins of screaming. I feel so bad and like I've failed everyone. Not being able to settle her has sent on into a massive spiral I'm struggling to climb out of. I'm currently on the sofa, in the dark crying by myself while everyone is on bed. I don't know the point to this just needed to let some feels out
