Does anyone else get stared at in public transport and feel anxious abt it?

I enlisted about 7 mnths ago and now in a stay out unit. My camp isnt close to my home so the journey is quite long. What I have noticed is that people keep looking at you and sometimes they even stare, and I am growing hysterical abt this, now I am constantly in an anxious state like I did something wrong and keep looking around cause of this anxiety build up, but at the same time I dont want to look weird by doing that so I have to hold my anxiety in. Sometimes now I think that people are staring me even when they arent. Anyone know how to deal with the anxiety while on public transport. Also why, just why, do they have to stare?
