Great!! It sounds like you have a plan and a solid one at that!!! Since you volunteer at church, maybe they'll support you starting a support group at your church for people with ADHD and/or other disorders to educate people with what you deal with on a day to day basis. You can inform people of what they can do if they have loved ones going through the same thing, so that they can avoid similar experiences. Be sure to invite your grandfather (and other critics) as well, so that he (they) can see that what you're going through is very real and that you're quite the busy young lady!!
Remember, you don't go through what you're going through just for you, you have to share your experiences to help others. That's why we're all here, and that's what connects us.
Well, it seems like you have a full plate with finding an ADHD coach/support, getting straight A's, finding out what works for you and what doesn't in managing your ADHD, and possibly starting a support group at your church. I'm so happy for you, and I'm glad my experiences were able to help you in some way. As yes, I'd like to think LHCF is a place where we do understand and care.
I'm really hoping the best for you, so I'd like to see a thread/post with updates on how you're doing with everything. Feel free to PM and add me as a friend.
It's getting late and DH has already gone to bed, so I'm signing off for now. Have a good night and I'll chat tomorrow.
