I typically avoid offering suggestions. My experience has been that all it does is create an opportunity, for the person who's asking, to list all of the reasons why that won't work.

Personally I have found that, the more one tries to get away from unwanted thoughts, the stronger they become. They're like little demons that feed off of the energy we give them.

My practice involves acknowledging negative thoughts with lovingkindness & compassion & then allowing them to drift away at their own pace. Over time they have a way of losing their power. (See my signature quote below.)
