If you are a Highly Sensitive Person and you often find yourself with one foot on the gas, and another on the brake, make sure you find the right balance for you between engaging in stimulating activities and resting. Also, incorporate as many sources of positivity as possible into your daily life as it helps to buffer stress and overwhelm. Take it as an act of self-care and make it a priority. These are healthier ways of getting and recovering from that thrill you seek without harming yourself.
