I am so very sorry she exercises her power over you in this way.
It makes my blood boil, knowing she has managed to make you " look bad" and like the one in need of a wellness check. I happen to think she is projecting her own illness onto you. I happen to think that SHE is in need of a wellness check. In fact, have you ever instigated a wellness check upon her? LOL!
I cannot tell you just how sorry I am that your own sister would pull this BS on you. I don't like her.
Much Love to You!
