Can anyone share some tips to overcome my stress and anxiety?

Hey folks,
Since the day I got engaged, I've been thinking about how my wedding would look like. But due to restrictions on the gathering of more than 50 people we postponed our wedding to next year.
We initially thought about still hosting our wedding with just a few people, but my fiance was not happy with our decision. I felt a lot of grief because I had been planning for our wedding over the months. Luckily we were able to reserve our wedding venue in Vancouver to the new date. We genuinely don't know when this pandemic will be over. Now I'm dealing with a wave of stress and worry that I would be affected by the pandemic.
I don't know how to overcome my stress.
Can anyone share some tips to overcome my stress and anxiety?
