Sometimes people just need a rest. From what you wrote, it’s understandable that you might want to withdraw for awhile to have some peace. But just as vacations need to end, so too does isolation. At some point, being isolated isn’t going to be a relief. It’s likely to become lonely.
Yes, there are risks. You might find it helpful to read The Lonely American: Drifting Apart in the Twenty-First Century by Richard Schwartz and Jacqueline Olds. They found that loneliness has been linked to an increased risk of cardiovascular disease and stroke and the progression of Alzheimer’s. A 2015 study by researchers at Brigham Young University looked at data from 3.5 million people collected over 35 years. They found that those who fall into the categories of loneliness, isolation, or even simply living on their own see their risk of premature death rise 26 to 32 percent.
You apparently need some coaching and support for finding and building relationships with healthy people who don’t need drama to feel alive. I hope you are talking to your therapist about how to develop mutually satisfying, healthy relationships. Medicine won’t do that for you. Developing some new skills is more likely to help.
I wish you well,
