Hi, welcome to the forum. You said you weren't on any meds for 6 months - are you on medication now? Having a lot of flare-ups means you might need some tweaks or a different medication altogether. Is your doctor aware that you keep having flares?
As for managing stress, for me I find that exercise works pretty well. Depending on how active your illness is, though, exercise may not be an option right now. If you can exercise, try something gentle like yoga, short slow walks, or swimming. Some people on the forum have had good results with things like meditation or deep breathing as well. Make sure to get enough sleep also, that can make a big difference. Make sure to laugh often, watch a funny movie or go to a comedy show, that sort of thing helps me a lot. Your username is very optimistic and I think that's great, keeping optimistic will help a lot too. I hope that helps a little bit.
