I never tried to convince anyone that it is their fault for whatever problems they encountered in life and sadly one of them died by an overdose in an early age. Perhaps ADHD contributed to their lifestyle of choice, perhaps not.
I am not impossible to convince that I am wrong, I have just never seen any evidence for it (I haven't really searched for it though). AFAIK ADHD is a disorder that we just don't know that much about and maybe it has a biological function that has been positive in the development of mankind.
As I stated, I am not a doctor tho and maybe there is loads of evidence for it in which I am not aware about but frankly I don't care much one way or the other. It's not an issue that I care about that much and I just wanted to share my take since one of my exes was completely convinced that I had it. I know that people with ADHD can be very successful and I don't think people should think less of themselves because of some diagnosis.
Please explain how I made the lives of my friends harder. By being their friend? You know nothing about me or my life. Being unfriendly doesn't convince anyone, you're just as much of an example of it as I am.
I just shared my thoughts since I at least have experience of it and if you disagree that's completely fine by me. I don't understand the sentiment today that you're not allowed to have opinions on stuff unless you're a scientist. It is imho impossible to be well read upon all things in life, sometimes all you have is anecdotes and experience.
