What will realistically happen if just let myself faint in public (irrational fear from panic disorder)

I’ve become agoraphobic and my main fear is when I start getting weird symptoms in public and I’m afraid I’ll present my physical symptoms in a drastic way and faint and I’ll either be ignored and not get help or someone will take advantage of my helplessness, or I’ll ruin everyone’s day.

What will realistically happen if I just stopped caring and fought through my symptoms and if I did faint I just let it be. Like in the aisle of a store or something or the mall. I’m tired of being stuck in my house.
