They usually don't advertise but if you interview therapists and tell them you need something less expensive they should be able to point you in the right direction. Next are schools. If you have any colleges in your area that have graduate degrees in psychology, they usually have low fee counseling centers where students train to become therapists. Last but not least are your local churches. Ministers and pastors are trained in counseling and usually offer their services free of charge.
Successful counseling feels like something has changed, something is different.
You feel more hope and self-confidence. You are trying out new behaviors and they are working. The way successful therapy looks is other people begin to comment that something about you seems different. Maybe they don't know what has changed in you, but you feel better to be around. You will also notice that you are having different results from actions that in the past would not have gone so well.
