Do you know how to show humility and be genuinely vulnerable?

I'm just open about my failings, tragedies, and misadventures, and don't really worry about being vulnerable or guarded. I show I empathize with people by sharing a similar experience I've been through. Its not trying to one up them, its just kinda my own way of showing that even if I haven't been in exactly the same place, I am trying to process what it must be like by sharing similar experiences. As for how I can be humble? Well, you don't really need to try if you just share your experiences as they are. We all fuck up, fall short, and herped when we should have derped. Sometimes it makes our experiences even more fun to share. And from my experience, its much easier to bond with people this way. I have my war stories. Some of them glorious that left even me impressed, and others are just downright pathetic in my mind, yet easier for people to relate to. I think making friends based on a "Yeah, I've fallen on my face once or twice, too" is much more fruitful than a "I stopped a zombie horde charge with nothing but a raider, a narrow alley, and a shit ton of darts, all by myself in HVZ!" But when I do tell the latter story, I tell it because its a fun story, not because I want people to be impressed by it.

I'm only vulnerable to people I trust. The constant scowl on my face from my many bad experiences seems to keep people away though so trust is a very tough thing to come across for me. Not always a bad thing but I might want to work on that a bit since I could do a with a couple more good friends.

humility is easy, but vulnerability is a no go, least irl even when i cry infront of someone, i try my hardest to laugh and keep a smile xD

Humble all the way. Tons of people cooler than me- probably you.....PROBABLY Vulnerability...Depends on who and the situation. Life is still about surviving, unfortunately everyone is not out for your best interest.

Humility is the easier of the two. Let your actions speak for themselves and don't go beating your chest verbally for every little thing you do/accomplish. Praise others for the things they do well and don't treat life like a competition at all times while comparing yourself to everyone and thing. Vulnerability is the harder of the two imo. It essentially comes down to trust and opening yourself up to others, and that's frankly something I still struggle a bit with. I have a hard time making new friends a lot of the time and still have a tendency to be introverted.
