Unable to trust anyone

In general I don't trust people easily, but I also always have a feeling somebody is going to scream at me to go away or something when I'm around people. Lol idk it sounds stupid but can't help it. I was kicked out of places sometimes in my life, like one time I was standing in front of a pub and the owner came out screaming to me to go away bc they were having a music concert or something inside and I hadn't payed so I couldn't listen from outside. Lmao I was just waiting for my friend, didn't even notice there was music inside wtf. Or the worst was when a guy send his dog after me, I still have the signs on my arm. I guess he thought I was suspicious bc I was around at night but still don't sent your dog after people. That was so f scary. Or the many times landlords did not want to rent me their place, that is so annoying. I'm always cautious around ppl, they make me anxious, that's why I go out when few ppl are around. Maybe all these things make me sound like a bad person, but I'm very responsable and honest. Where I live rules are very strict, they check how much time you want to rent a place and if you say like one month, they say no. If ppl don't know you, even walking in their street make you suspicious. They make an interview when you want to rent, and when you are young it's difficult to pass bc they think you are not going to pay or you're going to party and break things lol. Idk I just don't trust ppl that much, they can look calm and friendly, then they suddenly change and it makes me very anxious in general lol. This is my experience with ppl, I'm grateful to all the kind souls I found tho, y'all are the best!
