Is self-isolation selfish?

Isolation is when you stay to yourself because you have no idea who to trust and have no energy to give to anyone or uncomfortable with being pulled different directions and it’s depleting your mental health and energy. A way of healing and dealing with the sense of losing control of one’s sense of reality and self. Sometimes we absorb too much from people should be allowed to give to back and replenish ourselves especially since we know we can’t bring any positive energy back at this moment.
