Difficult to say.

No-one in my family knows much about it. I never say anything about it. After a while you get good at hiding stuff. The topic rarely gets brought up and I prefer it that way kinda. It's just something I can't bear to talk about....I start feeling really sad if I get asked about relationships from my parents. Now that I think of it, I think my dad only asked me 1 time why I never had a girlfriend before. I think I just shrugged it off. A few days ago I was going to talk to my mom about it all because there have been times where she would hear me crying late at night when I'm in my bed sleeping, but I'd just make up some excuse. My sister makes fun of me sometimes too. I'm very private with my thoughts and issues that I have in me, I'm also very good at hiding it. Like if I'm depressed about something, I can keep it in my mind and still act fine in reality. Okay I'll stop now.

I never told my family about LS, and I am largely estranged from them now.
I haven't told my friends about it either, although I haven't held everything back. There is one in particular who I have to wonder might be partially LS or incel; but if he doesn't come out and say so I won't assume anything.

friends

Not with me.

I don't tell my friends/family about this kinda stuff.

I think my mother secretly wants me to remain single till after 30, at which point, she'll start complaining about why she doesn't have any grandkids.

How would you like the support of your family and/or friends to manifest? Assume for a moment that the friend or family member is deeply sympathetic and wants nothing more than to help you. If it's a given that only people who are love-shy or incel can understand the issue fully then what can a loved one do to offer support either materially or emotionally?

My friends are worst idiots than I am, which is quite a feat.

My parents don't understand LS and trying to explain it to them is impossible.

friends

I've only vented about my situation to one friend years ago. He gave me some very generic advice, but was supportive. My other good friend has never really had a steady girlfriend as far as I know.

Aside from a useless tip from my father as a teen ("just ask them out for coffee" or something), no family member has given support or asked me about my love life (or lack thereof), ever. Can't blame them, as I think I give off some aloof antisexual vibe to them, like I couldn't care less about women or relationships.

As for my family, my sister and mother would sympathize but will be unable to offer anything valid. My father? He would understand intellectually but he would just give me the "You have to be strong for your mom and sisters" crap.

My "friends" would be overjoyed. They would negatively judge me and when they are down they will think, "Well, at least I don't have it bad as esoteric." They would just keep me around to make themselves feel better. I classify these parasites as leeches, scum that tear you down to bring themselves up. They would absolutely hate for me to better myself in any way.

No, fuck everybody. I can't rely on anybody and that just leaves myself.

P.S. Yes, I do realize I have a "me vs the world" mentality. Its a justified reaction when people trip you and laugh for their benefit and doesn't give two squirts a piss about my welfare.

For the most part, my friends and family are supportive. I can remember some people in my family though crack jokes once in a while. Example would be someone I use to babysit had gotten her first boyfriend and someone said something along the lines of wow, before you even. Yep, someone I babysat got a boyfriend before me. Rub it in. For the better part of my 20's I was fairly heavy, and I can remember some people saying I had to lose weight cause "don't I want a boyfriend?" I think it may of played some mind tricks on me, like I couldn't get a boyfriend while being overweight. Now that I have lost weight, I am still just as scared of sex and relationships. I'm still not tiny, or even small, but I am right about at the average for the US women.

Family - No point in speaking to them about my problem. They have dismissed just about everything I have said. Useless bastards (especially my siblings).
"Friends" - Never had any. Good thing; they would probably make me feel more homicidal than depressed.

All in all, I am alone. If given a decent option (that benefits me) at the cost of my family ostracizing me, I'd happily take that option.

Family: I haven't talked to them about it (nor do I plan on doing so).
Friends: Same, except I plan on talking to them about it sometime in the future.
