This gets under my skin

I posted earlier about being evicted from my home bc i was in a car accident and lost my job qnd could never recover financially. My brother stayed with me and he either paid no rent of half. My mom would always say well hes doing what he can, hes giving you something and blames me well now we all stay with my mom and im here until i finish nursing school.( 9 months) when it was time to be evicted my brother just left and never helped clean or anything ... anyway my mom gives my brother so much grace, she always ask him how hes doing ect not me.. anyway she said something that rubbed me the wrong way. My brother walks to work bc he gave his car away..she told my brothat he doesnt have to walk.. i can take him to work with her car. I have to be here until i finish school. Its irritating so i have to deal with bs. Would you say something ? If so what?@Lisa he.didnt try. I would understand if he lost his job and was unemployed for a bit but he kept giving most of his money away to church.. and then.when it was time to move he left 3 days early and went with my mom... but i agree with yall tho..gonna lay low.
