I had an efato a couple of years ago: the first few flights after the event I found myself keeping an eye open for fields but soon relaxed completely without any worries on further flights.
This June while touring eastern Europe I had the engine splutter badly five minutes after take off but made it back to the airport with no problems (rather enjoyed the fire engines chasing me ;-)
)
Had the engine checked out and took off again for a 3 hour flight over the Bulgarian mountains. On arrival at destination I was totally relaxed and flew the rest of the 12 hours of the trip, (including an hour overwater crossing) without any concerns.
Maybe knowing now that I don't panic and can handle unexpected situations gives me a certain peace of mind.
I'm sure you'll soon be back to enjoying your flying without feeling unduly tense
