Messed up and behind on premiums and now unsure if I will be covered

I cant really afford my insurance and I straight up wasnt paying it. I didnt even realize they had sent me a notice in December, a notice in Janurary, and a notice in April. I saw the 30 day grace period ended on April 30th. I freaked out and put together what I could (813) but still owe a lot left (2135). I did notice that Ive had grace periods end before, so I am hoping this is bluff? I can an additional 1,145 via my credit card and then the rest the next time I get paid on the 15th. Should I bother trying to reason with them or just cancel? My job requires me to pay put of pocket but also requires I maintain it. They dont really have a way of being notified if I lose it but hate to anxious for months before open enrollment. I was prioritizing other debts cause of the interest but I really messed up. Please dont be too harsh with me although I got myself into this. I promise trying to turn new leaf on my fiances 😅
