My Son Wants to Move Out

My question involves juvenile law in the State of: Colorado.
My son will be 16 years in a couple of months wants to move out of the house, he said because he no longer wants to live with me (his mother). He has been diagnosed with severe depression, is on medications and he has been aggressive with me in the past. I feel like I can no longer handle him, my daughter who is 8 years of age also has to put up with his behavior. What I mean by putting up is by him using offensive language and negative behaviors. He is going to individual therapy but it seems like that is not working. It is affecting me at work and in the house. I have tried many things, too many to count and our situation seems to worsen as days go by. When he tells me he simply does not want to be with me anymore I wish he just leave, but I am his only provider and he has no other family out here, so I continue to take his condescending behavior and I do not see the light at the end of the tunnel...
Please advise...

Unfortunately each situation is different. You cannot allow him to move out nor can he just leave ... you can just go get him back .. no landlord will argue & should pay you all the money he paid (and get it on the spot or call the cops).

Seek out help in the real world, not in cyberspace.

This is not legal advise
But you being his mother and if you think he might hurt himself or anyone in the household you need to check him in a mental instution where he could get the help he needs.
I have a history of servere depression myself along with PTSD and took a while for me to find the proper help.
