Male relatives anxiety

I’m confused about my feelings around my relatives and I don’t know what the root of it is.

I do love my family, but whenever I go to a family gathering I suddenly feel a lot of fear, anxiety, and insecurity. Sometimes it’s so intense that I want to leave immediately, and a few times I’ve felt like i wanted to break down in tears after i arrived and said hello to everyone

What makes it harder is that I don’t think they’re bad people. I actually care about them. But my body reacts like something is wrong and I can’t control it.

Sometimes I even feel sad or nostalgic when I’m with them, and other times I just hate the idea of going at all. I also noticed the feeling is stronger around the male relatives in the family, but I don’t fully understand why.

Because of this I keep thinking maybe I’m just being too sensitive or maybe I somehow created this problem in my head. But the feelings are really intense and I don’t know how to deal with them.

Has anyone experienced something like this with their family? Or figured out why it happens?
