I have been doom scrolling on tiktok and instagram for hours now.
All those perfect, skinny, good looking girls having the time of their lives.
How could I ever compare to them?
So depressing tbh
Yeah social media is cancer for mental health. I'm sorry it's doing this to you.
When your mind is getting bashed with negative information, it's good to step back and look at what is closer to objective truth than subjective truth.
Let's look at your concerns:
1.) The women appear to be skinny and attractive; and
2.) the women are having fun.
Now, these days even morons can easily touch up/Photoshop their pictures (some apps even do it automatically and they don't realize they're less pretty irl!) but let's assume all these pictures you're seeing are accurate.
I'm going to assume based on this post that you're a woman who is not asexual/aromantic. The main benefit of being skinny + attractive is to get sexual interest/attention, right? I mean, when it comes down to it, that's what your gut is telling you when you see pretty women and get a pit in your stomach.
With that in mind, let's look at this in reverse, and start with these women "having fun." Other members above have gone into great detail about how pictures of someone drinking on a boat does not mean they're happy, and that is absolutely true. I want to add that women in particular are more miserable now than in recent history. Some quick googling regarding women's depression, happiness, satisfaction, etc over time are all pretty sad topics. Clearly, people don't know what they want, and women have arguably been hit harder.
Now, I'm a romantic, and there's some personal opinion here, but also data to back it up: people are most happy when they pair bond with one special person as their life partner. It has nothing to do with wild adventures you post on Instagram.
Still, while that covers the "fun" concern, it doesn't really cover the attractiveness concern, right? Because with all of these pretty girls, what partner would pick you first? Some commented above that personality is more important than attractiveness and while that is certainly true in the long run, I'm sure it doesn't alleviate your concerns, because we've all seen sexy people with shitty personalities get favoritism in one way or another.
Remember, then, that you only need one good partner with whom you can make your own life where you don't have to worry about the misery-filled void that is social media. That doesn't mean go bone somebody and get hitched right now, but keep that goal in mind. Now, let me give you some truths about the dating game from a man's perspective (apologies if you're not interested in guys, but it should still be relevant):
1.) I have yet to meet a woman who - if she took care of herself physically - could not become attractive enough to get guys' attention.
2.) while this does mean not being very overweight, you absolutely do not have to be supermodel skinny. It's a lie.
3.) women do not have to be as high of a "rank" (1 to 10 attractiveness) as men to be successful at finding a partner. My theory is that the female figure is naturally more appealing, but regardless it's statistically true.
4.) while personality is important for long-term success in a relationship, initially the most important thing in the world is attitude. Everyone (but especially men) is/are discouraged from dating right now. People aren't having as much sex in the modern paradigm. Confidence is low. What that means is that a woman who will boldly approach and make her intentions known immediately jumps several points in attractiveness. (And no, posting tasteless, whoreish pictures on social media doesn't count. If anything that makes it more frustrating when she's a piece of wood irl )
Take all of this and combine it with this conclusion: in life, you need to be attractive enough to get someone's attention initially, then maintain attractiveness enough that they smile when they see you and are able to get off when craving. That's it. That's how much physical attractiveness matters, and someone can fall deeply in love with you if you are that attractive. Based on my points above, you can do that. I'm sure without even seeing a picture of you.
