I dont personally think it's possible to inherit mental problems from our parents but anything is possible i guess.

My agoraphobia stems from my illness (Labyrinthitis).

That would be my main reason for staying in so much that it became a permanent thing.

Though taking drugs as a teenager and a few traumatic events have probally shaped the way i think and that in turn effects how i deal with this.

Poppy, do you know why your agoraphobic ?
