Are these feelings normal?

My dad died on April 6 this year. I'm only 13. Is it normal for me to cry every night. I also start to feel upset whenever I hear about something that reminds me of my dad. Is that normal? I used to go to a therapist but I don't like it. Is that okay? I feel like I can't trust anyone any more even my mom. Do you think that I'm acting normal from what happened or am I overreacting?
