-He doesn't bottle it up unless you and him are on an expedition
-Otherwise, he will start acting more shy than usual, and once you notice, he bursts into tears
-He stresses how he feels worthless some days
-He clings to you as he tells you how he's afraid you'll leave him because he isn't good enough
-You pull him close and tell him he is perfect, and he always will be perfect
-It takes the longest time, but he eventually calms down in your arms and thanks you, hugging you tightly
