Feel like giving up

So my and my ex broke up she moved and left me to pay all the bills alone basically with nothing while we was together I didn't get a car because we both agreed it was to much money so now I'm stuck spending 20 dollars a day just to get home and to work I can get a bus pass for 70 dollars but the bus stops running at 6 I get off of work at 11pm it really stressing me out because I'm not rich and this is eating at my pockets big time I just don't know what to do I can't stop crying it's just a mess oh and we also work together
