Yo me encargaré de que estés muy contenta
I think of encargarse as "to deal with" , "take care of" like "no te preocupes, lo me encargo". Don't worry, I'm on it. I guess encargarse can mean to ensure too then? I will ensure that you are very happy? Gracias.

You are making a typical mistake:
encargar: to commission/order,
encargarse (de): to take care/charge (of)
There are thousands of verbs in Spanish that are different when they go along with a SE pronoun. Calling them reflexive is nonsensical and deceiving.
