How do I [23F] stop being scared of the men trespassing our backyard

I thought I would be brave and strong when it comes to this but it turns out I am a scaredy cat.

I was home alone this 10 in the morning when I heard footsteps around the house, and up in our roof. I was sure the men are back again in our backyard, stealing our fruits. We have avocado trees in our backyard just besides our roof so you would hear footsteps as well as banging sounds coming from falling avocadoes. I was home alone and was so scared I called everyone I could. I locked all doors, closed all our windows, and took a video of them from inside the house. I was seen by one of the men while he was smoking and hid from the camera. And so I got scared I ran inside my room and waited for the people I called. I was so scared my whole body was trembling and I wanted to cry. Our neighbor took pictures and got a photo of 2 men, one had a sword tattoo on the face. He demanded them to give the goods back and they did. Anyway, they went away after that and the police came 15 minutes later.

But my point is, I was all alone, scared, wanted to cry, trembling and was paralyzed. All I could do is lock myself and wait for help. Even now after the police left I hurried to this cafe a few blocks away from my house because I couldn't stay at my home alone after all that, and I still want to cry. I have always thought I'm brave and strong but when it comes to this why am I the opposite? I'm like a scaredy cat. I couldn't move, I was shaking, I was panicking, I was worried, I was so scared. I don't wanna be like this. I want to be strong. But, how??
