My Son is gone again

I am worried again I thought things were getting better but I feel like the meds arent working on my son. He left yesterday morning and hasnt come home it is 11:35 am. I have tried to call him but he doesnt answer his phone and when I call back he has turned his phone off. I asked him what he was going to do he said community service he told me he has been spending time at the homeless shelter again. I really dont know what to do at this point. I give him his meds they are the disolving kind so i know he cant spit them out so I know he is taking them. I am at my wits end I got him an appointment at mental health but it is not for another 2 weeks.

I was wondering if someone could help me? Is there a way that I can take over his decisions for him like make me his guardian? he blows all of his money he doesnt pay his bills and he is suppose to give me money for living here but that isnt working out. If there is a way to do it please let me know what I have to do.
