First things first
If you do have friends but feel like you dont youre probably overthinking it . Everyone's busy or has S/Os of their own they focus on more.. lol. Sadly. Also, social lives are overrated, anyway... Especially when youre still busy with schooling and work and need to rest more than go out. You may also not be looking in the right places, i find it difficult to make friends in school/class unless it's within a club and we share interests.
andtheres nothing wrong AT ALL with having only a few friends. Why do you need a lot of friends? What matters is the quality of the friendship! Not sure how old you are, but most friends you make high school wont stay in touch with you after that. Maybe for a year or two, then its byebye. Everyone's busy pursuing their own paths now. And socializing in college can be crappier... it's all partying/drinking. people who prefer having an active social life that involves doing drugs over their education annoy tf out of me anyway.. youre lucky if you find someone whos interested in the same games and hobbies as you, isnt about that lit life, and you can actually talk to and do normal things with though. i like joining clubs, especially ones that require me to work/put effort in them, to make me feel like i have some kind of social life, bahaha. youll find peopl that respect you and want to befriend with you through them also
i used to worry about being friendless also, but i eventually came to realize even my good friends i cant see or talk to as often, its NOT because we 'arent friends', it's nothing personal. were just all so busy. seeing each other once or twice a season is enough for me, considering weve all known each other more than 75% of our lives so far. and its nice to think that we will be friends for the rest of our lives also. honestly im not worrying about being friendless anymore , we should be worried about being financially stable in the future and keep at our education.
