Where's my motivation to live life?

I'm just now getting over a similar situation. Obviously its not exactly the same, as we are two different people, but maybe I can offer some insight. If you are in college, most universities offer free counselling. That is what really helped me, having someone to talk to who won't judge me, and knows what they are talking about. Maybe that is why you are posting this on yahoo answers. Don't be afraid to get help. That being said, force yourself to be in social situations, even if you really don't want to. you won't make friends at home sleeping in, or playing WOW. Friends are a huge influence on your life, I think if you find some friends who you can relate with, then you may be able to glean some motivation from them. Human beings are social creatures. We are not designed to be alone. Just being with someone can change your entire day. Get some physical contact, as much as you can, even if its just a high five or something (not creepy contact, just be around people and connect with them physically and socially)
