I have been dealing with the same thing for many years. I didn't know what to do and I would have terrible anxious thoughts all the time. Now,I have been able to stop the bad thoughts, the anxious thoughts, the fearful thoughts.
it's not medication. Medication calmed me down but I still had the thoughts.
First of all, if there's anyway you can get a book called mindfulness it teaches all of this. Secondly, what I do is when I notice Bad thought, I absolutely DO NOT react with anxiety! That makes you more anxious and more bad thoughts come. You have to Calmly acknowledge that the thought is there no matter what it is. then, staying calm, you imagine it floating off into the sky and dissolving . Do this anytime you get a bad thought. It takes practice but over time, it will be automatic as it has been for me.
you see, when you react with anxiety, then your brain becomes anxious and this actually produces more bad thoughts! The key to all of this is keeping the brain CALM! Anxiety and fear are the culprits behind the bad thoughts.
we can't let them take us over and we don't have to! We are in control!
something that helped and still helps me calm down our audio meditations for anxiety found on YouTube. I listen to them a couple times a day. There are many to choose from. I do like one called detachment from overthinking and another called clearing subconscious negativity. Listen to everything that is sad. There are many many others to choose from. Also, you need to remove your self from the thinking. Another thing is focus on your breathing . This is also taught in the mindfulness Book.
breathe in slowly through your nose for five seconds. Make sure your stomach rises .
then breathe out slowly through your lips like you're blowing out a candle . Think of how the air feels going in and out. Do several times and when you get bad thoughts. This keeps you in the present moment, away from bad thinking.
Be relentless and you will manage this well!!
try not to feel frustrated if you have one good day and one bad day. That's normal in the healing process.
REMEMBER: CALM the brain down and don't overreact to the thoughts. They are fleeting and not a part of you so you can get rid of them before they grow!! 😁
