Hi Wrecked!
A) Think of changing your username to something a bit more self-endearing ...
B) I wouldn't buy-in to your diagnoses of ADHD and bi-polar too much. It sounds to me like you were dealt a rough hand at some point as a youngster, got diagnosed with dyslexia then ADHD and then some point later, they added bi-polar to the list.
I'd recommend as a first step to look at reading some positive forums where others have shared experiences and resources in regard to dealing with and moving on from their so-called 'disorders' or 'diseases'. In millions of cases, there was no chemical imbalance in the brain in the first place and it's debatable as to whether ADHD and bi-polar really exist (yes, check Google Scholar, especially British Journal of Medicine) if you think what I'm saying is a little bit left-field.
We're all a little bit bi-polar at the end of the day brother - it's called life!
C) Don't hate people. Try to love everyone you meet as a starting point first. These types of feelings only manifest inside yourself and make your condition a whole lot worse. This will only make you even more unattractive to women than you already feel. Trust me on that one!
D) 24 years old is not old! Provided you're fairly healthy and don't die in some random way, you're only 1/3rd to 3/4ths through your lifespan! Man. Change that attitude right there. Over here in my country we say - "You're only as old as the women you feel". I'm 28 but the woman I feel is only 21

. Act like you're young and the world is your oyster and you'll freakin' dominate everything that gets in your way. Because you can - you're young now but you won't be forever. Achieve all you can now to set yourself up with serious self-assurance for future times when the body starts deteriorating.
Finally, work on yourself before you work on women. Or do both at the same time but only when you're feeling up to it and in the right state of mind.
Read some good books, study your psychological conditions (but don't OWN them or let them OWN you - that's not who you really are), go the gym, get a tan, buy some nice clothes, work on your confidence ... You'll be sweet.
Best to you man !! Be free and enjoy your youth ..
