Ignoring these thoughts is probably not going to be an option. You are coping with very strong emotions and that can be very distracting.
The feelings need to be acknowledged. You can do this by taking some time alone and dealing with how you feel. Start by writing down how you feel. Let what ever comes into your head go on the paper. This will help you express how you feel and see it at the same time, giving your thoughts a "voice".
Set aside some time to think only about what is on your mind. Concentrate totally on how you feel. Let all your thoughts and feelings come without interruption.
Once you do allow yourself time to think about how you feel, make a deal that you can think about how you feel later but it's time to work. You may have those feelings still there, but accept that they are there and let them be.
Take a small object into the meetings with you. Some people like to use a smooth colorful stone or a favorite object. Put the object where you can touch it and feel it as you need to. Whenever you have the intrusive thoughts, touch the object. Let it comfort you.
