I did take meds for quite a long time, but i didn't just have depression, unfortunately it was worse than that, but not going to go into the details, but after some years, they didn't make me feel better, only more sluggish, and zoned out, i found that if you get support, and believe me that's not easy to come by, as takes so long to get on one to one or group therapy but they can help. No one is every truly out of the woods, but GP is the source to start with, and take it from there.
Annie i wouldn't ask your personal details, like your age if you get my drift, so you could be young, but getting older can play its part too. Where menopause for women can be devastating, and for men who might go through a mid life crisis. All these things can be problematic.
