I've been going back and forth with my dad about how I don't want my sister around my daughter because I don't want my sisters bad attitude to rub off on my kid. About a week ago, my dad got mad at something I said and told me to find another way to work. I almost lost my job because of that. I was 3 hours late because I almost couldn't find a way to work. Thankfully my moms friend took me. I almost lost my job because of that meaning I almost lost my way of supporting my family. It really hurt me so I blocked everyone on my dads side including him his wife my sister my aunt and my mamu (what we call our grandma) on Facebook. I just recently found out my mamu is in kidney failure. I could lose her any day. I can't lose my mamu. She's done nothing to me. It was my dad and aunt who almost cost me my job not my mamu. I feel like complete shit right now. I just hope she can find it in her to forgive me. I really love her.
