So let me get this straight - your at your parents home staying with them for a bit to get some things straight in your head?
I think you need to forget about the rabbit for now.....I have lots of examples like that in my head that jump out to torture me about my perceived failings at anyone random time of the day.
I don't think it sounds like you have run away.
I don't think you are avoiding conflict either.
You have made a sound decision to go be with people who love you unconditionally and probably want to help.
You seem to be unwilling to be railroaded by your boyfriend into believing your habits are okay, nothing to worry about.
And you are going for professional help.
To me thats facing this hard on, head on!!
Many of us here, me included left it a lot longer in life and wasted lots more opportunities than you. A lot of us hid what we did too from loved one's.
Feel proud of what you have done so far.
Stay with your folks and let them look after you.
Give yourself a bit of room to think.
You can really turn this around if you want to and there can be really happy chapters in your story from now on.
