@Mymily - it looks like you're in the right place
This is a common question, frequently discussed here. Even Dr Sarno said that sometimes, you need a boost from medication in order to get on board, and the general consensus seems to be that if you take it with a short-term goal, thinking of it as a tool to get you pointed in the right direction, then it can be very helpful.
I'll also offer some alternative ideas, starting with a little book by the late great Claire Weekes, called Hope and Help For Your Nerves. It's slightly quaint, having been written in 1969, but it has really helped many of us, and literally thousands of people around the world, with anxiety. I think of it as the second book that saved my life, after Dr Sarno, because he didn't really address anxiety, which many of us now know absolutely goes hand-in-hand with TMS.
I would also recommend adopting a therapeutic breathing practice, very easy to research on the web, often incorporated into meditation apps.
Drink a glass of water or a calming hot drink (probably not coffee) while you mindfully relax and breathe. Meditation is very powerful, and not always easy for those of us with anxiety, but there are other ways to reclaim your equanimity.
If you're having a bad day, try taking an OTC pain reliever, even just a Tylenol. An interesting research study found that acetaminophen was surprisingly effective at temporarily improving emotional well-being. Some days, that's what you need. It might be a placebo, but the placebo effect is actually very powerful, and it can be harnessed with positive impact.
Hang in there and keep us posted. Your other supportive post indicates that changes are happening for you!
