Do you think. when my kayak eventually does flip over way out at sea. even though i have a lifejacket but?

i cannot really swim. do you think i will drown? i mean surely desperation will get me back to the kayak right? or i will just doggy paddle to shore? or maybe i will just really learn to swim well quickly. i think i can swim but not well at all. not at all. but i am still gonna go out to sea!
