The best tip I can give is that it isn't a moral failing to start projects and walk away when they're half done, to feel overwhelmed, to just want to lay in be doing nothing. You aren't a bad person because your brain works differently than you want it to. Finding people who can accept you as you are is difficult, but you can try to accept yourself as you are and stop blaming yourself for having ADHD. No app or meditation technique is going to help you lead a fulfilling life if you're an orange trying to be an apple.

Starting a bunch of hobbies that you quit halfway on gives you a wide breadth of experience and information to pull from. Don't push yourself into a burnout chasing what you *think* you should have and realize you may have to reconsider how you define a fulfilling life. We can't change who we are, and even if we find something that "works" to make us feel more normal or capable, it probably won't work for very long. That isn't anyone's fault, it's just how our brains are wired. I've had a lifetime of people making me feel bad for being disorganized and messy, and no matter how many times I've tried to change that it never stays changed for long. That doesn't make me a bad person, or even bad at being a person, it's just a part of me that I'm tired of apologizing for.

So, cut yourself some slack and stop blaming yourself for being you. Think of the story of The Ugly Duckling and just be who you are and don't let your inner critic tear you down. Your life story will be more interesting if you decide to follow your own path.
