What are so really good tips in not stressing so easily?

i come to realize that i stress over situations that are out of my control i stress on future situations before they even take place i have a visions in my head how things are going to happen and nothing looks good so i stress. i also stress if plans that i made did not go through and it would be something as small as just going out to a party i've notice that i would get to the point of a breakdown because things would backfire on me. so i was wondering how i cannot stress over situations that are small/ over my control are there any good tips in not stressing so frequently
