Judging by the content of your five previous messages you've posted on here, I think it leaves little doubt that you are actually depressed to some degree. If we assume this to be true (that your suffering depression) then we can deduce that the poor hygiene, the anxiety and the poor self-esteem could simply be repercussions of the condition. It's widely known that people diagnosed on the Autism Spectrum are far more vulnerable to things such as depression, I've even read people suggesting that's its hardwired into a minds.
Personally, I've struggled with it immensely and lived a very miserable year of my life before identifying the problem. I on some forums some time ago where I received an excellent piece of advice that has definitely changed my life.
I was told to go get a small notebook, a piece of paper, anything that I had on me at that particular moment and write down what I wanted to do with my life. After several weeks I had compiled a list of things I wanted to do, or skills I wanted to have. Some of them included: Music, Programming, Writing and to learn a second language then travel. I had little to no experience with any of those at the time.
Despite the simplicity behind this approach, I think that it is extremely beneficial and thought that it might help you!
You have to find out what you enjoy, what you want to do, and go do it. Set some goals and strive for them.
It's not what is bad, it's what is good, that we should be focusing on and devoting ourselves too.
