Random thoughts and emotions that are all over the board!

I am an adult child of an alcoholic father.  I have two grown children, and 3 grand children.  I have been a Christian since my early 20's, and I attend church regularly.  My problem:  Random thoughts and emotions that are very painful at times, and are all over the emotional spectrum.  I have gone to al anon enough to know that my family of origin was very broken.  How do I help myself, and my 6 siblings?  Five of them don't profess Christ, and I struggle daily in my relationships with Him and others.  Most of it is inward, which is very unhealthy, and I feel like I am drowning in negative emotions and feelings most of the time.   Please HELP!
