I feel depressed inside

I generally have a good life. I have a good job. friends and boyfriend. My family life at home has always been rough, my dad cheated on my mom when I was 14 and I never felt the same spark and joy inside (I’m 23 now). When I left for college and was my own person I felt close to my old self but since moving home my joy has just depleted. I don’t enjoy my life and I don’t treasure the little things like I used to. I don’t know what to do. I don’t trust anybody because my dad was living a secret life and it has scared me so bad that I can never relax because I feel like there’s something going on that I don’t know about. I told my mom I think I have anxiety and depression and need help and her response was to listen to calming music. I don’t think she knows how I truly feel inside because on paper I have a nice life and I should feel happy and blessed but I have so much turmoil inside and every day is a struggle.
