Friends are highly over rated. I've been on both ends of the spectrum through out my life, being a natural introvert, I was forced out of my comfort zone when I had to move to a communal woman's refuge. From then I learnt to be more extroverted, I've seemed to attract "friends" like flies round horseshit. Most only call when they need something, or to offload their crap or gossip of others. Which can often impact me negatively. I have one friend who has problem after problem, will offload until I'm physically drained often after her own downward spiral of actions which could have been easily prevented had she taken any advice in the first place. My assistance to her family court hearings and so forth. I keep my distance by choice these days and envy myself when I had no mates and was obligation free. I deal with my own problems head on myself and I would rather go without than borrow money, so why should I compromise myself for others? I'm also not as naturally needy of company for the sake of company as some of my friends along the way. Accepting its not a natural trait of my personality to have friends has been key, because I'm really not! I find it tiresome! Draining! I'm also wary of others which does not help. I'm coming to the realisation distancing myself and having little to do with my mates has improved my mental health!
So I wouldn't be too concerned with not having any, especially if you want without. Social media certainly does not help. But in contrast look at those who do not boast of such social interaction. It will certainly be much more higher, those that dont! Also when I have been in great company, I've never ever documented it on social media!
You're best off with a dog or a cat if it is nice company you want.
