Women Only!!! What's wrong with me?

Well, I think you answered your won question. If you are in therapy and taking medication for your depression, then you should be able to work through your own demons and eventually you will allow yourself to open up to someone else. Its okay to like solitude (I love it, in fact I keep all of my phones on silent to avoid being disturbed most of the time). But, you have to appreciate the company of someone else. I think you're only robotic because you havent met the right woman to bring you out of your shell. Eventually, she willl come to you. For now, just work through your problems and the rest will follow. Good luck :-)
