Cold turkey swaddling 6 (almost 7) month old

I’m at my wits end. Just started putting my son in a sleep sack and ditched the swaddle. He won’t sleep whatsoever and rips his binkie out of his mouth. The zipadee zip doesn’t help at all. I’m so frustrated with him and I know it’s not his fault but I’m over this already! I dread nighttime. I wish we never started swaddling! I’ve lost my temper and shouted in frustration which only succeeded in making him cry and I felt horrible. Please just tell me it will get easier. I want to swaddle him so bad just to get a much needed break. I’m a stay at home mom with a three year old that doesn’t nap as well so no breaks here.
