Yes, meditation helps. It can help anybody. I don’t do it regularly but sometimes I feel my life getting a bit out of control so I meditate to restore balance. I have tried to meditate to progress in my life and health and at times I felt blocked. That is OK. You can come back to it at a later time when you feel you are ready to receive its benefits. It is a very personal thing.
I’ve practice mindfulness meditation through the Calm app, which I think is worthwhile, and I did a transcendental meditation course. Both techniques can help you restore balance in different ways. They’re tools and you need to learn how to use them. If you don’t feel like its working, put it aside but remain open to it working later down the line.
Modern science does not satisfactorily understand how or why it works, but people have been doing it for thousands of years at this point. From a mechanism of action perspective, different techniques synchronize brainwaves differently. From a symptom perspective, there are plenty of studies showing it can improve mood and anxiety and other things.
I’ve honestly overdone it where it has destabilized me in the short run so I recommend to stay open minded and take it slow to see what you can handle and what works for you. It’s an art, but there’s real science to back it up.
