One thing that actually helps me is meditation. So long as I meditate every single day without skipping a day I can go a long time without anxiety and depression. Longest I've lasted was year and a half. If I stop meditating I will gradually revert to my old habit self and then anxiety returns including strong depression once or twice a year.

Maintaining mental health with meditation drags every other aspect of myself into the same basket, I stop eating meat and eat lots of vegetables and fruit, I drink only water and don't consume anything processed, sweats etc. and I exercise 7 days a week.

Then I get better, physically, spiritually, mentally and emotionally and I feel like nothing can beat me. Then I skip a day of meditation, then two days and before you know it I'm eating burgers from McDonald's and skipping exercise, drinking Red Bulls and smoking. Then I'll have anxiety/panic attacks before bed, insomnia, depression and after struggling with myself for a year I'd change my lifestyle again.

But then I get well again and forget about the struggle and the cycle repeats. It's a living hell.
