Estoy alivio finalmente vengo a recuperarse de este misterio enfermedad

Question

"I'm finally relieved that I'm going to recover from this mystery illness"!

Does it make sense and is it correct, could be constructed better'

Answer 1

"Alivio" is a noun, and "estar" cannot be used with nouns. "Misterio" is another noun, and it should have been an adjective.

The most common way to say this is probably:

Menos mal que voy a recuperarme de esta misteriosa enfermedad.

Using relieved:

Por fin estoy aliviado de saber que voy a recuperarme de esta misteriosa enfermedad.
