Oh I can relate to this super well although I'll be "only" 30 in June.

Like you, I have no job(my social anxiety has kept me from looking hard enough), never even been on a date and the emotional toll of loneliness and lack of affection is significant, friends I have...well hopefully I still have the one, but I don't know at the moment.

I don't think 35 is old but, let me tell you, I understand perfectly well why it seems that way and your feelings are completely valid. Nowadays when it comes to making a family, getting marriage type relationship and so on, there's plenty of people who don't even consider it until their mid 30s, so there's definitely still a good chance you'll have that if you want. It's also not too late to get a job, although depending on experience it might be a little harder at first.

It's definitely not true you're pathetic though, I'm not pathetic either(I'm not going to say there isn't plenty of people in society who would think that, just that it's not true), because of course there's a tendency to compare and assess our place in the world and our achievements with those of people around us in society, that's normal and society does sort of push this thing where there's "rights of passage" so to speak, different moments when you're expected to "level up" and a lot of people will do it more or less. But then, a lot of those people didn't have quite the same issues either. Some of us, we had some extra baggage to carry around, rubble to dig through before reaching the light. It's like starting a race a mile back from everyone else, there's catching up to do and in the end you've ran more.

Sure, I've always been aware of that lack of experience when it comes to my own life, I do feel like in certain situations lack of of some of the social experience most have, is a downside and I worry about it and yes, it does start to become noticeable, but it's not something we can't catch up with, just need a little bit of luck along with trying to do our best.

I don't have much energy either but I hang on and do whatever little I manage to do, I try because there's no other life, this is the one and if 30 years were more or less wasted, I want to at least not waste them all and everyone deserves and should experience some happiness and love in this life. Don't beat yourself up if you can't do a lot right now, that's ok when you're lacking resources, just think on what you could do. You're definitely not old at all for that.

We can talk further if you want
