Testo originale - Inglese - I will rise again

I'm wanting to get a tattoo and the latin for "I will rise again" is really important to me but I need it to be accurate! The 2 versions I have are "Resurgem" and "Resurgo" so I'd like to know which it is.
I've recently come through depression and want to mark this time on my body to remind myself that there is always a light at the end of the tunnel.
