Frustrated and sleep deprived

My 7 week old won't sleep longer than 30 minutes at a time the last 2 days. He's fed, changed, burped, snuggled. Just wants to cry even when I'm holding him. He does have gas, but I've tried everything (gas drops, gripe water, probiotics, bicycle legs, tummy massage, etc). I'm not sure if it's his tummy or what. He sleeps in a bassinet next to our bed and has since day 1 and it didn't use to be a problem. I'm at my wit's end here and just getting increasingly frustrated and sleep deprived. Plus no one to really help. Thanks for listening to me vent. Any advice is welcome.
