CJ:
Great to hear from you again. Sorry you are going through this. Meth is really a plague. I never had any curosity over anything like that, especially after what it has turned my sister into so I can imagine you living in a neighborhood infested with it. Sounds like your landlord is also using, if not she may be profiting from it by being paid off to keep her mouth shut or she may just be afraid of putting her foot down to these thugs.
I can't think of any other solution other than what some of the other posters already told you. Move. I know it may be next to impossible for you to do so financially but you may even sink further down if living there causes more damage to you or what you have left, vehicle and personal belongings; not to mention your dog! In places like that you never know when there will be a shootout and you, your dog or partner may be caught in the crossfire. I hope you can get out of that mess soon. Please keep us posted!
