I think suppressing feelings is underrated.

Ideally, you clear them but the only other options are suppressing them, distracting yourself or going postal.

And by going postal I might mean doing some exercise, being artistic etc.

Oh right this is the meditation forum.

Well I clear them but if you can't do that in a few mins without messing up your meditation, this is what I was advised: encapsulate the thought in a bubble and let it drift away. Repeat as necessary.
