Post diagnosis/medication observation

I just wanted to share this as it's been on my mind a lot recently. I started suffering 24/7 panic attacks at the age of 14. I was misdiagnosed with anxiety/depression for 23 years. I've been on every Ssri and Snris, didn't give me any relief. I have suffered immensely down throughout the years. Addiction issues, severe isolation, constant burnouts and mental breakdowns.I booked an Adhd assessment last year and got diagnosed with combined type Adhd. Started on methylphenidate and....panic attacks have suddenly stopped, that horrific catastrophizing rumination in my head has been turned down by 80-90%, I can look people in the eye and have a conversation.

Why I'm posting: My sense of self(if you want to call it that) was derived from that rumination, rumination that included paranoia about meeting people, insecurities,grudges, all those other horrible painful modes of thinking etc.

Since starting methylphenidate it's like my entire existence has been jerked out from under me. I have a quiet head. It's so weird and strange. I don't even know who I am anymore. That insanity in my head was undiagnosed ADHD. Is this how other people experience life?

I feel a small glimmer of hope that maybe now I can live a normal life. I'm writing this to see if other people can relate to how I'm feeling as I feel very alone in this right now.
