I was homeless for 5 yrs. Taking a bath is not getting the dirt all off. How can you clean hard to get out dirt from your body?

Realize that you are physically clean, what you are trying to get rid of is the emotional and mental dirt from having been homeless. Since you say you were homeless, past tense, you must not be now. It is in the past, can not hurt you and you have to let it go. Learn from whatever caused you to be homeless and move on. It does not have to control you.
