You are not a horrible person. (((((((((((Silversparrow)))))))))) Sounds like it isn't a good environment to be in... families fight sometimes, but if it becomes too much then it ceases to be useful (because venting is helpful) and becomes toxic.

If you plan on spending time at a friends house, how would your family react? Have you done it before? If you're serious about going - please leave them a note telling them where you went and how to reach you because they will worry.
