I'm very sorry to hear that this has happened! Did they block you on all the platforms?
That's really challenging. Please make sure to take care of yourself and your wellbeing too. I'm really glad that you reached out to the forums. Hopefully you can find a way to ask them why they blocked you. Sometimes this can give closure but it may also be painful too.
What is your support system like? Do you speak to your family about these things?
