Dear plain_jane,
Just reading your initial message and I am so sorry that you are being used and abused by others. I don't know your personal story - bit I do know that your body belongs to you and no one has the right to touch you or abuse you in anyway. And even using you for emotional support can be abusive. Sometime when we are vulnerable, abusers find us easy prey to take advantage and/or abuse us. Safe and unsafe touch applies to all of us. You deserve better and you have every right to say no. If you are at risk or danger, please reach out for support.
Happy to chat if you would like to talk things through - please feel free to dm me anytime.
Take care.
