Solitude has a feel good quality for introverts.
This kind of sensitive nature is hard to balance when control or lack of control is a problem.
To tune out when over stimulated takes practice, as does being around people and connecting socially when only the loud are heard and rewarded for their behaviour.
Knowing yourself and doing no harm helps one maintain control and let go of overstimulation with lots of solitude and down time.
This kind of self care or self parenting is the kind of behaviour this kind of personality will need to practice for themselves.
