Having Problems With My Visa for Bolivia

Hello, I arrived in Bolivia in May and started the application process for a special purpose visa ( volunteering for 7 months). I still dont have my visa and there was another error so i have to reprocess it, but im taking a trip out of the country soon, so that is going to be delayed until october, and I am panicking that my visa wont be completed and back to me before i am scheduled to leave the country. Is there any way to change my visa type at this point and just be here on a tourist visa???
