Am i ready for a half ironman? What is my next step?

Some of yall may remember me. Im the dude who lost 200lbs and finished my first sprint triathlon. Ive set a goal to become an ironman and am working my way towards that goal. Since then i have completed a sprint triathlon, a 42 mile cycling event, an olympic distance gravel triathlon, and sunday i will complete a full marathon.

Do you think im ready to pull the trigger on the half ironman? Or should i plan for something else before it? Im wondering if i am ready. The half iron i have picked out is in june. I think i can do it by then if i swim all winter long.
