How to get over the stress of eating alone as a woman???

i am currently on a two week solo trip around Europe and I am having such a great time!! so many incredible places I've been, I'm truly enjoying every part of it...

...except when it comes to eating in public alone as a woman. no matter where I am or what part of Europe I'm in, I can't help but feel like eating alone as a woman is wearing on me. it's made me sad but lately I've just been eating in my hotel or hostel because of how much I can't stand it. between the unhelpful or downright rude treatment from waiters, being pushed into corner seats or bad bar seating, the stares from patrons, the unwanted conversation from men when they see I'm alone... i just can't shake it off any longer. I can't STAND IT. I simply don't see men eating alone getting the same treatment in public. I've tried bringing a book, I've tried wearing sunglasses, I've tried listening to music the whole time but I think the experience has just worn me down.

ladies, what are your best tips for eating alone in public?? in just want to enjoy my meal without feeling like a leper!
