You gotta untie yourself from something. Make a choice which is more important to you.... The things tying you up or the desire to interact with others. Good luck.
I would like to interact with others, but I don't have time to do so since I'm very tied up. What can I do to make it possible?
Quickly untie yourself before your assailant comes back . . . .
If that was just a metaphor, then assign your priorities from most important to least . . . You may have to shift these based on what each means to you.
Don't give up. Keep trying.
You have to make time. If there is certain people you want to socialize with maybe set up a time where everyone can get together on a weekly basis. If you want to meet new people join a group that meets on a regular basis. Then you can easily schedule them in, and schedule around that time. At one point in my life I was working 50-60 hours a week. My husband's job took him out of town 1-2 nights a week. We always made sure we were home and left work behind on Friday evenings. We often met friends for drinks and then dined alone. It allowed us much needed socialization and time alone. We made it a priority. Often one or both of us had to be at work on Saturday morning.
