Well, Al-Anon is free, so that make it worth considering as a starting point. If you grew up around alcoholics, you will find others who will understand and give you the tools to deal with the consequences of that in your own life.
If you find that after giving it a fair amount of time, Al-Anon isn't cutting it completely, you could then look into some additional therapy. My guess is that much of what you are dealing with has to do with the alcohol issues, so someone who is familiar with that might be the most helpful.
