Narrative:

I was training on the local control position at the time of the event. I had approved a pointout with aircraft Y 8NM northeast of ont in-bound to poc on the ILS approach. I received release for aircraft X while aircraft Y was 5 northeast (260 KIAS) of ont and cleared aircraft X for takeoff. The aircraft X pilot did not take the runway as quickly as I anticipated and I attempted to get a vector for aircraft X approved from sct. Sct advised they were 'unable' to issue the vector. After quickly scanning to see aircraft X's departure status; I noticed the aircraft had barely begun to move forward and cancelled their takeoff clearance. Due to the added stress of the government shutdown; and not knowing how I am going to keep myself and my family fed and housed; I may not have fully evaluated all of my options; and may have reacted to the situation more slowly or logically if I wasn't worried about when I would receive my next paycheck.allow ont tower to utilize dva's [diverse vector areas] without sct approval while still in ATCT controlled airspace.
