If you want to call and talk to me, be prepared to say what was going on in your life when the depression started. Common causes of chronic depression are being unloved by parents, broken love relationships, deaths, worry over money, failures, self blame, guilt you laid on yourself or accepted from someone else, etc. Guilt is the most devastating. Being broke or out of a job does not qualify because that's an ongoing stress you need to take care of on your own. I have nothing to sell, but I do ask for feedback on the results within a few days.
