Finding a space without the stress is of utmost importance. Please consider meeting with friends, vacation, hobbies as a mode to de-stress. The family conflicts could be a reason for you to feel emotional numbness because it keeps you safe from having to deal with more emotional stress and some unsavory details.
Next Steps
Please see a counselling psychologist for an evaluation and further course of action. If you are feeling suicidal, then you should go to the nearest hospital emergency department and see a psychiatrist immediately as it is an emergency situation.
