That doesn’t look like enough protein… What does your workout schedule now look like, how often do you workout, how often do you switch up excercises, grips, db/bb/cable ~ how often do you switch your main leadoff excercise ?
Do you ever train with a partner.
I suggest this ~ decide if you really want to make progressive gains - Rededicate, refocus, and reorganize.
then…
Get more protein, baking chickenbreasts isn’t difficult, or double scoop ~
then…
Immediately find a workout partner that can spot you through the gates of Hell. So he can push you and help you do lots of assisted reps. Hell… if you go to the gym so much and haven’t made any friends to help spot you, get to it! A training partner is awesome to have, I try to kidnap friends, acquaintances, and strangers for my evil diabolical workouts.
and lastly - probably the most important thing : drop that emo state of mind, and visualize a powerful, strong, focused self again.
if worse comes to worse and your struggling through a rep, say OOOOHHHH YEAHHHHHH~~~ SNAP INTO A SLIM JIM!!
