Not sure if it's a phobia but it's weird

I get scared of walking in front of other people. Like, if I know there are people walking close behind me, even people I know, I get anxious. When I was little my parents used to beat me behind the head when I walked in front of them lol. I think it's bc of that bc I also get the impulse to cover my head when I hear someone near me. Lol I know it's so weird! Like, my parents did that bc I was a lively child, and you know when you like walk-jump around as a kid? I used to do that thing, in front of my parents but they wanted me to walk on their side or behind, not in front so they hit me and I stopped doing that after some time lmao. But sometimes it happens that you walk in front of others, you know? Like when you're in a big group or it's crowded and such. So I get this phobia when it happens lol. I know it's so weird but I rememeber my head/neck hurting. And because it was from behind I couldn't see it coming when I was a kid, so it scared me every time! ╮(￣▽￣)╭
