Try to tune them out. I know that doesn't help much to say, but head phones, or just trying to find a place where they wont be. Ya always got me to talk to if you need it. I'd gladly give you my skype, and if you have telegram I'll add you there too.

Please be safe and take care of yourself. That being said, going to your grandmas is not the worst idea. If you can tough it through this night I would seriously consider finding a way there (Through your parents or otherwise) From what you have told me she sounds like far better company than what your folks have been providing.

If you need anything dont hesitate to message me, if you can get me on skype use my phone.
