I’ve always found it helpful to never push down how you’re feeling. When you’re having a bad moment through out the day I think it’s important to recognise and acknowledge the way you’re feeling in that moment so it doesn’t come back up later, if you push it down it will only come back up later and it’ll only be worse.
When you’re feeling anxious try taking a moment away from the situation you’re in and just take a deep breath and always keep a positive affirmation or even a nice quote to remember through any moment when you’re feeling a little off, one of my favourites is ‘I’m great full for my life and those who support me.’ And another would have to be ‘hold on, pain ends.’
Although in some situations we cannot always step out of to take a breath, I’d suggest using your senses to take your mind off of what is making you anxious, by doing this you focus your mind on something like what you can hear in the moment whether it’s people talking or birds, or the sound of music, talk to yourself in your head and say what you hear, taste, smell, what you can feel (try touching your hand/palm and acknowledge the wrinkles you dint usually) and try focusing on what you see.. These are such simple things that help me and that I use when I am able to catch myself feeling anxious.
