I think I have strong mindfulness, I actively do not think about work or things like "what ifs" by forcing myself not to

I always try to remember that doing something is rewarding even if the anxiety makes you scared of doing it. My self talk works for me and it might not work for you but I think to myself "wtf are you going to do all day if you don't do the thing you wanted to do".

So in summary: practice mindfulness, find a way to self talk and support yourself, remember when you were anxious but tried something and enjoyed it
