I guess i would be considered part of the older generation, but understand where you are coming from. I don't know if people will ever truly understand what we go through every day. I was always told what a looser I was and that I was lazy and would never amount to anything for years. I knew I had potential and that I wasn't lazy. Then I found something I liked doing and went beyond my own expectations.
Be very selective in who you share your condition with. People DO NOT understand, but they can, and do, use it against you to their advantage. I was fortunate to fall into a career that I loved and thrived in it. When I started in my position I was by myself and was able to find ways to hide my ADHD, reading and writing problems from others for almost 30 years. It wasn't easy, especially since the job requires writing and reading top with being I one of the first women in my field, but I did pull it off.
Lately can't get a grasp on my ADHD. Basically because someone discovered my faults and turned them against me. Everything I did wrong they wasnpointed out, then it became an attack. I let it get to me and lost control of my coping measures. So please, watch who you let know and try not to let what others say bother you. I know how difficult it can be though.
Once you find something YOU like to do you will find it easier to get up and do things. I was trying to get motivated for the past couple of years, had to loose weight after my husband's death, and I felt terrible because I put on so many pounds. I just couldn't do it. Then I found gardening, who would of thought, I stay in the yard and garden from sun up to sun down on my days off and lost tons of weight. But I couldn't force myself to get off the couch and on the treadmill for anything.
Hang in there, you will improve.
