When you have no control over your emotions and sometimes have trouble showing them
1 My friend Michael said he was happy about his new girlfriend but didnt look as happy
2: Today i found out that i am have Unstable emotions when i cried withno tears but a smile after being hurt
When someone is mentally unstable and don't feel human
His mental health is to unstable that he could become an unstable entity
That feeling when you drank too much red bull
Carl: Hey bro I'm insanely unstable.
Kyle: Yeahhhh...you might need to see a doctor..
