I am feeling very empathetic to someone this week who sometimes I just want to run over! lol 
Well that is kind of you. They must really be going through something.
They are mentally ill and the mood swings can be a bit much and seem intentional...as they tend to take it out on me..When they are being good though..it's hard not to be compassionate
That would be a lot to deal with. I hope things stay good for awhile.
