Hello. Só leigheas. Brene Brown has given a number of TED Talks, including this one:
I urge you to listen to this one and the Houston talk she refers to. Thereafter, I also urge you to get a physical and referral for a psychological evaluation with the understanding you will get treatment for whatever is indicated.
I have had experiences similar to what you describe. It was not until I started Acceptance and Commitment Therapy (ACT) and Mindfulness meditation that I started to have hope for a better life. ACT is challenging. It is worth the effort to help you become the author of your life.
I wish you well.
