I too suffer from ADHD with both depression and anxiety. I also think that I have begun my journey with CTE after a play hard life filled with well over a dozen concussions. I have been struggling mightily with severe anxiety attacks for the last 8 months or so, which for someone known to be pretty go with the flow, has been a horrible experience.
There are days where I feel that my gummy usage (I keep it at a consistent dosage of 12.5mg of THC per usage) is the only thing keeping me from blowing my brains out and other days where it makes me feel like they make my bad cycles worse so I haven't seen it as the be all/end all answer for my situation. Sometimes it just makes me run through endless cycles of self loathing where I can't let up on myself and I just beat myself up over the things I should be doing differently. Other days it is the perfect tool to help me focus on an enjoyable task in more depth and range. Still trying to figure it out.
Like anything, there's good days and bad. Fingers crossed for more of the good ones. Good luck to you.
