What’s the best way to deal with negative thoughts?

I’d say to try to recognize that all of our thoughts are not meant for us to attach to. If a certain negative thought keeps coming up, maybe try writing it down and asking “is this true?” Also, remember brains tend to have a negative bias as a means to survive so it’s important to actively look for positive things. I personally feel practicing gratitude is a great way to get present and combat negative thoughts.
