hi, i can relate to your situation a little bit so i think i may be able to give you some advice. i'm also diagnosed with aspergers syndrome and suffered from depression from the ages of 13 - 16, so luckily only two years for me, but i still know slightly what it's like to be in your place.
so advice from a friend - you need to stop seeing yourself as anything other than 'normal'. i promise you, we are normal. the fact we have a disability (if you want to call it that, it's also fine if you don't view it as one) doesn't mean we aren't normal; if you always see yourself as being a certain way the way you act, your thoughts, and your habits are all going to cycle around that, too.it's difficult at first, completely changing the way you think and altering the way you see yourself but it's not impossible and i promise you it's so, so worth it.
i know what it's like to see aspergers as a curse (i did for the majority of my life, too), but in the end... the harsh truth is, it's not going anywhere. so, i mean, why not learn to just love it? so what if we're a little different, and we can't speak like other people can - yes it makes relationships harder and maybe social situations a little awkward, but doesn't that just make the people who do talk to us and hang around with us just that little bit more special? they may not be with you now, but i promise you there are people who will love you and talk to you regularly regardless of what makes you 'different'.
no matter how tough it is, i would recommend at least trying to let some people in - it doesn't have to be in massive chunks all in one go, it doesn't even have to be offline. good people are out there, people who will see you for you, it just starts with you maybe opening your mind to the possibilities a little bit.
i guess what i'm trying to tell you is... the road to getting better starts with you, in the end. nothing will change unless you let it, which you can - it's possible, and i believe in you! since the above poster gave some really helpful advice on dealing with depression, i'll leave that out for now, but i did just want to give you some advice on loving yourself and your aspergers.
