Be careful, it's a down spiral, and I am speaking out of personal experience. You will, if you continue on this path, create a vacuum around you, and someday, you will wake up from the haze you are in, and find out that 10 years have passed you by, that you don't have a partners, you don't have friends, and that you spend most of your time conversing with someone inside your head.
You should force yourself, even if you have to fake it, even if you find interactions with people hard, and that their conversation have no or little interest.
Consult, speak to someone you really trust, but don't get isolated, it is VERY VERY VERY harmful.
