Suggest Treatment For Anxiety And Fear In A Person

I need help rehabilitating myself, I ve spent my adult years in fear, with severe anxiety, relationship issues and with some type of incompetency (Learning problems) that have led me to be one relationship away from being homeless. I have no friends or colleagues, I only have the few remaining family members I have some what of a relationship with and I can t even keep a job anymore. I need to know what my first step should be for someone who is 34 years old and is basically needing to start from the beginning in life again.
