Mocking religion

Asalamu alaykum ww hope your well. I have a question with regards to the validity of my marriage. Alhumdulilah Im practicing and I recently made a joke about one of my friends who over ate and puked. I said whilst in a group of my other friends that so and so puked whilst he was in ruku position with no intention of mocking the ruku position or making fun of it. I spoke to my cousin aswell who has studied ilm for 7 years in Leicester and he said I don’t need to worry and that my marriage is valid. I keep getting waswas about this and although I knew I didn’t make fun of the religion I will certainly not make any reference like that again in the future. Do I need to renew my marriage or am I fine? I’m really stressed if you can answer asap. JazakAllahu khairan
