Struggling with Emotional Support from Family

Today I woke up and started sobbing immediately. Which sucks but I think I would be able to more effectively deal with my emotions if I were able to process them, but I also woke up to a text asking me to pick up my little brother. (For context, my mom just left state to visit her sister who is going through treatment for cancer, and her mom who has Alzheimer’s.) I responded that I woke up crying and could barely even get myself out of bed and I was met with anger from my dad. A sarcastic “you Poor thing,” and then when I said there was no need to make fun of me, I woke up crying, and really didn’t need any more criticism. My dad texted me back that he was pissed because my mom is gone and he would have to be late for work. I’ve been progressively feeling better as the day goes on but I can’t shake being bothered by getting criticized further after being in an already emotional place. It’s hard not to let the weight of feeling like every problem is my fault weigh down on me but I’m chugging along
