I will never have that. I will never be able to form a palpable connection with another human being (aside from close family, that is). I will never have real "friends", the closest they'll be are acquaintances. I will never know the feeling of being in love. The simple act of socializing is physically draining and as a result, I will never "enjoy" events/trips the way normal people do.
Little late to the topic but: Does anyone ever really?
To be honest, you sound more anti-social overall than autistic (low social) functioning. The thing is if it is merely the latter an autistic person can learn to be more highly functioning socially. Anti social issues are harder to address I'd argue unless it's a combo of both being true as well, but all three scenarios just require pushing over your comfort zone to improve upon:
As a heavily anti-social person who understands those feelings, some things you adapt too some you just never care too and it doesn't hurt in the first place.
In regards to friends a lot of people call them "fakes" but most people are fakes. Very rarely do you come across genuine "honest" or "loyalist" and that's not even a problem just among anti-social people but normies especially. Being in love is a hit or miss thing if you're hurt enough times it can damage that initial feeling or you may just be drawn to some where you kind of vibe: again as a person who started low functioning socially with my anti-social behaviors I believe you can do it too, it's just a random chance to be honest.
I agree on socializing in person is draining it's why I've always hated hanging out with multiple friends and groups of people myself, generally when in such situations just ease yourself and don't push too hard into it and you should be fine, sometimes grass is not so green on the other side of the pasture despite how it looks.

When it comes to social interaction the best advice I can give in both regards (friend/relationship wise) the friends you aquire always trust but at the same time always verify when things seem suspicious don't be afraid to challenge friends, it keeps them in line.
Relationships, treat them as passively as possible, the ones who make it easy and rarely a hard strung fight are usually the ones worth indulging in.
Don't worry about interactions at social events, I don't, I would suggest getting used to public speaking though if you have a problem with that and if you are autistic and low functioning learning how humor works if it's an issue.
Whether you're autistic or low functioning socially both will still apply.
