Como dizer "Eu tento muito não usar isso" em inglês

I was talking with a friend and I don't know how but we mentioned google translate, so I said that:
"When I really need a translate, and I don't found anywhere, I search on google translate, but I try a lot to don't use it. Principally when is expression... google is terrible to do this."
He answered me and say this:
"I think the right form is I TRY TO NOT DO/THINK/..."
I agree with he, but "do" and "does" aren't used for negative and affirmative sentences?

Thank you guys, I hope you understand, and PLEASE correct anything that I could spoke wrong
