Dont sweat it, I was the same, although I never tried to find help and didnt really find ways to get better. I took meds a while back but I stopped for no reason.
But even then, now I can plow through my sadness all and only because of the strength my Lord gives me. It took me over a decade to feel clean, sincere, and loving to our Father. Even then, Im learning everyday.
A measly, its going to get better, wont help out. Stick with the Lord and then do of what is your duty for God. Surely then you will get joy. We all want to be happy, but surely Christ was not so happy being crucified. Even then, he never turned away, faith is huge, its love. My life isnt always going to be happy, through the best and worst may we give thanks.
