If you are homeless try to go to a psychiatric hospital ER, explain your situation and they have to help you or refer you to care available where you are. They may admit you so they can evaluate you and get you the proper treatment, medications and counseling. I don't know where you live but that is the way it works in America. They may also be able to refer you to a free clinic that can help. I pray for the best for you. Try not to focus on your current problems but on the One who can solve All problems. Stay focused on those positive things in your life and not the negative. There is always something good in our lives we can be thankful for if you just look for them. God's blessings to you and try to keep your chin up.
