Warning :this hurts (Bubble play)

[TheAmp]

Party 50 + 5.

I think my raise is bad - if I am going to an call all-in I might as well push. I really didnt know what to do here.
I have a strong hand, but on the other hand, short stack is about to bust. Is folding the correct play? I think this would be wrong since the short stack may double up while I lose the blinds. I would miss this hand. Also, I am not just playing for third. If I wait too long, I will not have enough chips to play with ITM.

Q : would you move in here?
Q : if not push would you call or fold?
