As someone who only made it through life with their abusive grandparents (lived with them) by having the internet be their coping mechanism and support system, I heavily relate to this, especially the roleplaying parts.
If it wasn't for a roleplaying forum where I met two of my best friends (who I have gotten to meet irl a few times now!), I'm not sure I ever would have gotten up the courage to leave. But knowing that even if I moved to my Dad's to get away, to escape- that I'd still have my online support system to give me, well, support, made it at all possible.
If I had never met these "strangers" online, I... don't know what I'd have done.
But now I am out, and I know myself so much better! and I am happier than I ever could have been! So please, anyone out there suffering, know that it CAN get better. You are not alone.
