Feeling ugly and antisocial on solo trip (22F). How do you guys combat this feeling

This is so shallow but it’s really affecting my self esteem and enjoyment of the trip. I’ve been backpacking Western Europe for the past 5 weeks and packed like three pairs of pants, two sweaters, one nice top and a dress. Every time I go out/see girls at my hostel, they look stunning, polished, well dressed, and make friends fast. Im only 22 and feel like this should be the prime age to make friends at hostels and look attractive on my trip.

Multiple people have insulted my appearance on this trip, including a guy who said “I look like I work on a farm??” At a club some guy literally waved me off and kissed these stunning, heavily made-up women on the cheek. And none of the cool, pretty, fashionable girls wanted to be friends with me. I clicked with the quieter girls who didn’t like clubbing, but I really wanted to make friends with extroverts. I was honestly just a magnet for drunk thirsty guys who wanted hook ups.

My acne got really bad on the trip too, and I think I’ve been gaining weight. I just feel so ridiculously unattractive and out of place surrounded by these girls. I know I had limited space for packing and had to be practical, and that the girls I spoke to were on shorter trips. I’ve really enjoyed the trip but this aspect has been killing me. I genuinely think Im ugly af after this.

How do y’all avoid feeling this way, and is it common?

EDIT: you guys are mean :( I didn’t want to go on dates or hook up with anyone. I have insecurities that came out unexpectedly while solo traveling. Damn I guess I don’t have a community here like I originally thought.

Also I am fairly thin and in shape, almost underweight so the weight I’ve gained has been negligible just feels weird on me rn
