The following context is from the movie "The Wolf Of Wallstreet" by Martin Scorsese
JORDAN My job, you know, it's tough. I mean I'm not complaining, it's just the stress. All these people depending on me. Millions of dollars at stake every day. I sometimes feel I've bitten off more than I can chew.
AUNT EMMA You're a man with large appetites.
Jordan looks at her and smiles:
JORDAN (thinking) Is she fu*%#ng hitting on me?
JORDAN I agree. I put it on myself. It's hard to control the anxiety, you know? It's hard to learn to relax.
One of the synonyms for the word "put" is "impose" (to force someone to accept something, especially a belief or way of living{source Camb dic})
Does this mean that he "imposed it on himself"?
