CBD oil I just use a tincture that I apply under my tongue - I'll also occasionally add edible capsules if I feel a day is going to be particularly stressful. From my experiments with THC as a teenager, we didn't mix well - I also used nicotine for a very long time, I wouldn't recommend it though!
For WHM I also do cold showers - I wasn't a fan at first, but now most of my showers are cold. I will note that I live in a fairly tropical climate so "cold" here isn't exactly freezing - I'm interested to see what the experience will be like towards winter as the water temperature will gradually drop. I do find I get the most out of it during periods of breath holding as it really let's me empty my mind.
Lack of healthy relationships can be huge - due to expatriating and people I knew leaving the country I am in I don't have a great deal of close friends who live in the same country as me - I am however happily married.
None of these are absolutes and it has taken me a long time to get to where I am.
I will also readily admit that in many areas I have been exceedingly fortunate and as a result there are many things I don't have to worry about that others do, this naturally makes some things easier - all our paths are unique.
How did you change your mindset? Books, articles, techniques?
I currently employ THC to help with my baseline anxiety but that has been going downhill for me recently. May give CBD oil a shot. Do you just vape it?
When you say Wim Hof Method, do you include the cold therapy or just the breathing?
I wonder how much does lack of healthy relationships (romantic or otherwise) plays a role? That has been my biggest problem.
