How are we coping

I know I probably sound like an awful mother but how do you cope. I’m a single mum and I’m really struggling to cope with my little boys behaviour. He is one and no matter how much I childproof my rooms he seems to always get upto no good. I can barely even go to the toilet withought him ruining things. He’s 1 and as much as I tell him no it’s naughty or distract him he just laughs at me and die it more. Since having him I feel like I’ve lost myself, I struggle to get a bath, bad time is a nightmare, I’m just about managing to cook twice a week (thankfully I do a lot of batch cooking). He’s well looked after but I feel like I can’t look after myself. My weight is out of control because I’m eating so much processed food or quick meals, I’m a constant mess because I nearly never get to do my hair or makeup or shave. I feel like I just don’t know what I’m doing. So many people I know can just put their child to bed with a bottle and then relax in the bath but mine awake til 10/11 at night, he won’t lay in bed with a bottle, he won’t sleep unless he’s in my arms for half an hour before transfer to his crib. He’s 1 years old and I thought it would get better but it seems like it doesn’t. I’ve tried to cry it out method and he just cried none stop to the point he vomits and can’t breath. I’ve tried soothing him and repeatedly putting him back in his crib and same thing happens. I’m at a total loss and could use any advise you have
