I'm pretty socially isolated, I am yet to achieve full-blown hermit-status but I am pretty close.
Here are the basic rules I live by:
- Don't leave the house unless you absolutely have to, such as medical or dental reasons.
- Face to face interactions should only be with the people you share your house with, and even then you should still spend most of your time in your own imagination or on the computer.
- Online interactions are an acceptable substitute for face-to-face interactions, though I realize that even these can become too much at times. If you need a break from Internet socializing, it would be wise to warn your e-friends of this beforehand, or they may become worried/upset/angry with you.
- You will likely find solace in a nocturnal lifestyle, as this minimizes your chances of having to socialize with your housemates, and the absence of sunlight and noise from traffic and other "daily life" sounds will greatly reduce sensory overload. If you are naturally diurnal, however, you may find solace in waking up in the wee hours of the morning rather than staying up until the wee hours of the morning. Basically, find out what sleep schedule feels right for your body and try to time the hours to minimize socialization and sensory overload.
