Don’t think I’m cut out for this :(

I just had my 2nd baby 2 weeks ago. I’m a SAHM and my husband works away 2 weeks at a time and is only home for 5 days and back to work. I am struggling because my newborn doesn’t ever stop crying. I’m lucky if he naps once during the day. He is on nutramigen formula. I can hardly tend to my toddler because my newborn is always crying. He doesn’t like to be worn all he wants to do I swear is cry and look around. I dont have any support because my family all works. I already have depression and am on medication. I can hardly even cook my toddler a meal because my newborn needs my attention. I just feel like I can’t do this.
