I have been diagnosed with C-PTSD, depression, and anxiety since it's all a package deal lol. I've been doing therapy and self-help on and off. I used to be more on top of it, but as I've gotten better, therapy isn't as much of a need for me. I used to do it weekly, sometimes twice a week. Now I do it whenever I feel like I need that extra help.
It's almost impossible for someone like me to "cure" their trauma since everything happened when I was so young, and it kept happening till I was around 15. Healing, in general, for a lot of people, is something that takes their entire life. It's rare to see people say their trauma or mental illness was "cured" unless it wasn't affecting their life that much in the first place, in my experience.
I would say therapy has been the biggest step in my healing journey, so I would say it was worth it for me. My therapist focused a lot on cognitive behavioral therapy and internal family systems, and that helped change how I view the world and myself. I am in a lot better place than my previous lifestyle! I have a healthy and loving relationship and a lot of healthy friendships as well, so in general, I have a way better support system. I used to self-harm and do a lot of risky things since I was passively suicidal, and I don't do these things anymore, nor do I feel the want/need to. I am happy with my mental health and general lifestyle; the only thing I really worry about now is college, and that's how it should be for someone my age. I even started working out lightly since it helps my dopamine levels to get out and move.
This is all a big switch from what my old life was! I don't wanna share too much of my trauma online since it is deeply personal, but everything I stated was basically the opposite back then.
