Hi VF
I'm not gonna lie, the depression isn't just going to go away on it's own. FT is right-- oxy is a fantastic anti-depressant for a while. But as you found out, it stops working eventually and the depression will be there waiting for you. You've gotta work on that-- either through NA, counseling, religion, something. Depression does not just fix itself.
Having said that, we're all here to give you a hug. You can do this. Just take it day by day. It's not only a matter of not using, it's a matter of finding ways to be happy with your real life. What works the best for me is enjoying things that I could never do high. What did you used to love doing that you gave up because of the drugs? What have you always wanted to do but never got around to?
And never forget why you quit in the first place. Write it down if you have to because it's easy to forget.
Granted that's easier said than done. I'm a chronic relapser who's still on suboxone. But maybe it's true-- those who can't do teach
Hang in there!
