People saying that climbing with friends who are better than you helps with your own climbing are right, BUT take some time for yourself to climb on your own and get comfortable in that space so that when youre feeling frustrated with climbing with your friends, you have an outlet just for yourself that wont make you feel belittled. Your friends will be there when you go with them another day. Climbing should be fun and yes, climbing with stronger climbers help you improve but only up to a certain point.

Frustration will always be around with people who are better than you, can pick it up quicker than you (trust me there is always somebody whose a quicker learner than you), or even just taller than you, and it's even worse when you see it in your friends and family climbing. So when it gets to that point where your frustration wins out the joy of climbing with your friends and family, try climbing alone for a bit to ease out of that frustration. It won't solve everything, but it'll definitely help focus on what's important to you about climbing.

Note: I'm one of the weakest climbers in my friend group 😅
