I'm losing my mind.

Im a SAHM and it's literally getting impossible to entertain my son. He has a play may, sit me up seat, bouncer, rock n play, teething toys, books, and other little toys that make sounds. I'm finding it harder and harder to keep him content for more than about 15 minutes after playing with something for about 15 minutes he starts crying. I have a moby and I baby wear him. But Im starting to feel like I have to hold him constantly and stuff for him to be happy. I even let him watch a little tv just to try and keep him content for a little bit. It's driving me crazy though. When I first got his play mat he stayed under it for 45 minutes now I can't keep him entertained I read to him, recently just started going on walks to keep him happy. I need advice. Is this a phase? I love playing with him and stuff but I want him to be independent as well.
