Sleepless night... Again

So my little guy was sleeping fine on his own and in his bassinet at night and for some naps during the day, but for the post couple days he won't sleep unless being held. My husband is currently working 6 days a week and 12 hour days so I don't get any help at night and I am beginning to go crazy. The second I try putting my lo in his bassinet he screams until he is picked back up. I have slept a total of 2 hours over the past 2 nights and I am at a complete loss of what to do. Please any help/suggestions are welcome.

Sincerely, a very frustrated and zombie like momma
