Stay at home mom... going crazy

I’ve been a stay at home mom for almost 2 years now.. we have a decent size home but no back yard and barely a front yard.. I don’t have a car so I’m just in the house 24/7. Fiancé works 6-7 days a week and sometimes doesnt come home until 8:30p-12:30a. I just feel so bored. Like ive been rereading books, singing songs, playing with dolls, just over and over and over again. People say I must feel lucky to just stay home and not have to work, and yeah it’s nice but after a while it’s like I’m just here.. just existing. I want to go out and do fun things with my baby, take her to the park, take her to the zoo. Unfortunately, getting even a cheap car right now isn’t in the budget. Im just stuck here for now, repeating my days
