Anybody ever tried a mental coach?

curious if anybody has ever tried mental coaching to help build a better mental game in sales. high highs and low lows are typical in sales and I've typically been able to keep myself at a 6-7 but lately it's been tough. 

feel myself slipping with burnout lately- but quotas don't go anywhere and neither do bills. vacations are good but feel like they can be more of a bandaid than a solution. open to suggestions, but I've heard mental coaching can help with strategies for the long term to avoid burnout but also maintain high performance. 

I'm in Canada FYI so any online/ local solutions are helpful.
