Your claims as I understand them: 1. Lack of social skills. 2. Lack of ideas what to do with your spare time (at least I see it this way). 3. Lack of challenges and meaningful tasks in your current work. The 1. is only a problem if you pay close attention to it and refuse to go out because of it. The solution I see is to find a hackerspace (or similar association) nearby and just drop in to hang out with others. You'll get socialized, you'll find new areas you can look at and most probably it will give you an inspiration and new ideas, all at the same time. This could solve your 1. and 2. problems pretty quickly, and in the long run, either 3. will become unimportant or you'll find a better job.
