A first time mom of a 10 month old..?

my boyfriend and i are down to one car now when we first were together we had 2.. but his car died and he does not have the money to fix it so we just took it to the junk yeard.. so now we only have 2 cars.. so i am stuck home with the baby all day long.. and we were talking the other day about getting a nother car but then just relized we dont have that kind of money.. i need my own car i am going crazy... what should i do.. if i want to do anything i have to wait until his mom gets home or if she has the day off. its drving me crazy.. we live in Augsuta Maine and he has to drive to portland maine every day.. its to long of a drive to go back and forth to drop him off then pick him up agian.. cuase he dose not get out of work everyday at the same time.. and right now its winter out and i cant go for a walk its to cold.. and we live to far away from any stores..
