Having a tough time relaxing

Obviously, I’ve cut out all of my vices like smoking and drinking.

I’ve tried stress relief tea but that just made my stomach hurt. I just keep eating but I’ve gained to much weight and my dr told me to stop eating so much!

I come from a family of drinkers and smokers and they are trying to convince me it’s fine yadda yadda.. but I just don’t!

Are there any kind of teas I can drink that will help?
