Using Aquarium fish as therapeutic hobby

I'm 25 I've struggled with depression and anxiety since I was a teenager and I still struggle with it today I went through alot of bullying in school it still effects me I basically shutdown and I turned away any help but after having struggled with that I found my love for fish keeping in aqauriums and I fell in love with my Betta fish companion and he's more than a pet to me but family and a friend who I have with me all the time and it's changed me way of thinking and of life and happiness and it helps me to cope with my mental health problems that I struggle with and I named him Optimus my therapist named Carla suggested that I would start an aqaurium to help me learn to cope with my anxiety and depression and it's really helped me
