I understand that you are going through a lot of distress. This is particularly a difficult time for you as staying at your parents' place brings a lot of traumatic memories from childhood. As you have gone through negative experiences growing up, your mind and body can react to the current stress in a similar way to the past/as a child. I request you to find good support systems like your partner or some friends who can help you cope with the difficulties. Engage yourself in self-care by following a healthy routine and doing things that make you happy in the present. Set emotional boundaries with family members when they violate your personal space or personal rights.
Next Steps
Consult a professional/Psychologist to work on your thoughts and emotions and to find healthy ways of coping with stress.
