Im homeless...

So I've been holding this in for a while because I dont want my family to worry about me but our lanlord is selling the house because he is having financial problems right now and gave us 3 weeks to leave his house (where I live there are no homes available) its July 4th weekend and we are officially homeless. I feel so sad and depressed and my family does worry about me (also because im having stomach problems and have been going back and forth to the doctor) but we are struggling and I told my grandmother to use the credit card my school gives me for school supplies for a hotel but she refused (my mom doesnt know I got the card because she'll use it for cigarettes and her stuff) she doesnt want me to spend any more money because I used my money from working to put food in the house for now and she feels bad.. My father is a deadbeat and my uncle hasn't grown up yet and my mom tries but she doesn't make much(in the commonwealth, they havent changed the salary)
