Separation anxiety?

Anyone struggling with their babies separation anxiety?! My son is super clingy, picky with food too and gets super upset (and cries) when he doesn’t get what he wants or he plays with something and can’t with it anymore (we redirect). He wakes up many times overnight in his crib. He rarely sleeps overnight without being comforted (held and patted by me ONLY). And he only wants me to hold him and not my husband so I am EXHAUSTED. His crib is right next to our bed and sometimes he also wakes up when he sleeps in our bed ): Wah 😫 HELP!
