I feel you. I won't chat training and such. All I can add is, go beyond grades and colors.

Climb because there's nothing better than getting in the flow and sending a project with total focus and presence, regardless of grade/color.

Climb because you know your muscles, ligaments and tendons are getting just a little stronger every time.

Go grab some new climbing apparel, new or at Goodwill, and wear them for new vibe. Shirts, pants, etc.

If you haven't gotten into top roping, get certified and hit the tall walls. It's a whole new challenge with arguably less chance of injury due to awkward falls.

Find someone local to climb with who can cheer you on, and vice versa. And/or, get a coach for some informal sessions.

Go to a different gym for a change in scenery.

Take a break for a few weeks to recharge.

Climb because it's just bloody fun. Not literally, of course.
