Mum guilt - am I doing enough?

I didn’t mean to write so much but I’d really appreciate if you could take the time to read and comment your opinions <3 So I guess im just writing this to get some reassurance that I’m not alone in this.. as I do get really bad guilt from it and don’t feel like I’m doing my best for my daughter. My daughter is almost 1 and I’m currently 25 weeks pregnant, I’m always tired and exhausted as my sleep schedule has gone to shit. I’ve only been managing to fall asleep at 4/5 in the morning and have 1 nap during the day if I’m lucky. I feel like I don’t spend enough time with my daughter. I don’t go out much but I have been trying to abit more but it’s hard as I live on the top floor of a building with no lift and a narrow hallway so I can’t have the pram downstairs and have to carry the pram, my baby and the bag I need to bring out with me. When we are at home, she spends a lot of her time in the cot playing with her toys and watching her nursery rhymes on the TV. She’s always been very happy, always distracts herself with her toys, sometimes puts herself down for naps, she’ll cry when she’s hungry obviously or when she wants some company. And I do try give it to her, I’ll bring her in my room for an hour or two on my bed and we will play with her toys together or I’ll have the TV on for me and have her playing next to me. And sometimes I’ll cuddle with her and nap with her. But I still don’t feel like it’s enough. I feel like I probably would spend more time with her if it were for the fact of my living room being cleaner, so I could just have her playing on the floor and crawl about and stay in there with her.. but my ADHD and the tiredness have not been helping keep me very tidy, and the fact that my daughters dad just makes messes and doesn’t help me at all around the house or with his daughters, as he uses the excuse that “he works” ( 9-5 ) so he shouldn’t have to. And I’m also the only one paying the rent since we moved in so it’s not like he can use the excuse that he provides for us as he always blows his money on himself. And as much as I hate the word and don’t want to say it, I almost feel like I’m neglecting her and get really upset at the fact that I feel like I should be doing more, but I find it so hard to.. It would help reassure me knowing I’m not alone but at the same time if I should be doing more, I would like honesty and the hard truth as maybe it would give me the motivation to get myself together more. I’m going to start trying more regardless, because I want nothing more than to be the best I can be for her.. but I just want to know.. is anyone else like this? Or am I actually.. being a horrible mum?
