"Aviate, Navigate, Communicate.."
Deal with the problem, do what has to be done, let us know, (but do it ASAP please).
The vast majority of units have radar or ATM (Aerodrome Traffic Monitors) avaialble and any ATCO worth their salt will realise if something is wrong by observing the departure profile on said facility, equaly they should be prudent enough to wait for a decent interval to let you sort out the aeroplane and your thoughts.
