@CheeseyToasts - what is the point of these posts?
You’re taking op’s negative perception of herself at face value, when there are plenty of reasons to suspect it isn’t the full story.
We cannot tell if op says she has no interests because she’s undervaluing her interests, because she’s low, because she’s not making or doesn’t have time for herself or because she really doesn’t have any. I tend to think the last is unlikely because whenever I’ve met people who don’t get interested by much they seem pretty contented. It’s also not a personality type that dictates whether you have friends or not - people like that very often slot into groups without making waves. I’d be surprised if the op doesn’t at least have the capacity to develop some interests. She needs to overcome whatever is holding her back.
A lot of your other claims that are overly simplistic too as well. No point in hobbies? I’ve done loads over the years, and almost all have had a social dimension beyond simply doing whatever the activity is, even if it’s just going for a meal at the end of the course. Great for building up confidence and social skills. And if the op was so introverted that she couldn’t join a hobby group she’d hardly be worried about not having friends. I suspect you’re referring to social anxiety rather than introversion, and while that might make it difficult many people do successfully push themselves out of their comfort zones to join groups.
And the silly birdwatching comments. You come across as very insecure sneering at stuff like this. Reaching adulthood and feeling the need to proclaim how saaaad other people are when they’re affecting you not one jot is pathetic.
I wouldn’t usually engage with this sort of rubbish, but I hope the op reads all the posts challenging it. Because it’s garbage.
