Get out more. Pick a hobby that requires some kind of interaction - the drama class is a fine example - and then commit yourself to it for at least a year. You don't need to "relate", or "understand" other people. You just need to recognize and develop an appreciation for their point of view, even if it doesn't make sense to you. The best way to do that is to immerse yourself in it. If "people" were a new programming language that you needed to learn, how much would you dedicate to learning it? If it were a language that you would be required to use for the rest of your life, how much would you give to it? It won't be easy, and it won't come all at once. I assure you, as someone who has gone through all of this, that it is totally worthwhile. Professionally and personally.
