Taking care of your appearance

So I’m 21 & idk wth happen to me. I’ve come to the point where i don’t care what i look like going out. I do care. But not enough to take time & doll up. In high school i use to wake up two hours before i had to catch the bus to make sure i showered, did my hair & makeup & had cute clothes on. Even when i wore sweat pants i dressed it up with a cute cardigan or high socks with my ugg boots. Nooow... i can go out with what i was wearing to bed and not even wash my face. Idk if it’s because I live with my bf and we have a baby so i just think life is complete i don’t have a reason to look good anymore?? Or if i just got use to being lazy with my appearance? Well today.. we went to grab food and i stayed in the car while he went in and a girl from his past saw me & i was just so embarrassed and felt so insecure and ugly😔 i felt embarrassed for my bf tooo.. because i won’t lie the girl was cute, her body was right, she had such clear skin & here i am with an oily face, hair in a bun with sweat pants and big shirt waiting on my fried chicken... i need advice on how to start caring again.. it’s like i care now but tomorrow when i wake up i probably won’t care.. and it’s so hard finding the time now that i have a 3 month old. When she sleeps i sleep... ugh i need help. I’ll drop a few old pics of me when i first met my bf my.. i feel bad because the girl i am now isn’t the girl he met.

This is me now 🙄

This is on a decent day.. but I’m so white my hairs falling out I’ve gained so much weight!! Ugh need advice ladies 😩
