I am writing a paragraph about why I want to participate in this school counsil thing and I was wobderi if the word choice for "deticate" in this sentence makes sense:

I want to deticate myself to participate in more school activities.

Opps I mean dedicate*
Yes, you mean dedicate. Your sentence would be better if you said,

I want to dedicate myself to more school activities.

Also, note that it's not a "school counsil thing." You probably mean student council. Using the word, "thing," is disrespectful and shows that you don't know much about this council.
