If you really have the feeling that you want to change your lifestyle then you should be the one to take the initiative. You asked us here to give you some advice. But still, in the end, you must be the one to take some action. Also remember to take one step at a time. Changing yourself and your lifestyle is not as simple as ABC but rather a hard work and needs lots of patience. And never ever try thinking of suicide >.< There will always be a speck of hope even if think that it is already gone.

Here are some suggestions of what you may possibly do:
First of all, try talking with your family. They are your family and I am sure that they are willing to help you overcome your hiki-state. If not, then they should not be called family.

If that doesn't work, try finding friends online. Due to the internet, we are actually closer to you than you think. Try talking to them through the microphone if your messenger has the function. Who knows, you might just meet someone and a possible solution from the both of you might come up.

You can also attend anime or manga conventions in your city or country if there's one. It is a good place for people with the same interests to meet and talk about things.

You can also try finding your dream job out there. Finding your motivation can really help change a person. A dream job for someone who likes games/anime/manga could be a game tester, a manga editor, or even a mangaka :D... The world is actually a pretty big place. You just need a powerful imagination and you could become a great person.

Hope that helps... Remember that your feelings and determination to change greatly affects your performance.
