My parents have offered to pay for a therapist. But, they are also helping with the financial issues, so I feel REALLY guilty about putting that burden on them too (did I mention that I am particularly prone to guilt?). They have been a rock, even though my wife has tried to wedge them out of my life and denied access to the kids.
It might be worth thinking about taking them up on it. While you think about it, you can read the lessons here and post here and try to get a better grip on what it is that you are dealing with for the long term.
How do I go about finding a support group? I live in Houston, so I would think that it would be a big enough city.
It really depends on what kind of support it is that you want. You mention that she drinks. There are support groups for family members of alcoholics. You mention that you have been drinking too much. There are groups for alcoholics if you think you fit that category. There are 12 step groups for just about everything you can imagine. If you want to deal with issues of Codependency, there is CODA.
Here is a link to a therapy group in the Houston area that has a sliding scale fee. They might be able to point you towards some free support groups too:
