Hi Gene,
I know the depression curse well. I suffered from depression most of my life...but never got it treated until just recently. I either didn't know what was wrong with me, or I was in severe denial and couldn't admit to myself that something was wrong.
However, once I made the decision to go in for treatment, I got my life. I don't say I got my life back, because I don't think I could ever say that I was ever happy. I had periods of happiness, but I never had what I would have called a happy life. To this day, I still see a counselor and am taking medication. Together, they work wonders for me and have helped me become the person that I want to be. There is a better place we can all get to if we are open to the methods that can help us.
It sounds like you are on the right track...and I promise, GOOD THINGS WILL FOLLOW. You've already made the decision to see a doctor. You've already admitted to yourself that you have depression and PTSD. You told others about your suffering, which is the ultimate sign of admission. You are even open to the idea of taking medication. You've done everything you can to help get you to a better place. You've done the hardest parts already--the admission and having the willingness to find help. The rest will take effort, but you're already on the road to recovery and you've already made a lot progress.
I wish you all the best in your recovery. If you ever want to PM me about anything relating to depression, or airguns for that matter, please feel free to do so. I'm in Alabama, which isn't too far from SC, so maybe one day we can get to know each other and go out shooting.
