Reality checking is strategies you can use to check if somethings real or not. Ie. I heard someone downstairs working on our bathroom pipes, I live on the first floor therefore there's no downstairs. So it was in my head after that I could ignore it. If I hear or see something odd that my dog doesn't react to I know it's not real. Waking up in the middle of the night to check if my husband is still there and not cheating on me when I sleep. Things like that.

Safety plans are things you can do/people you can call instead of hurting yourself.
