Consult a psychiatrist or clinical psychologist and get assessed about the past trauma and how it is affecting you now. Psychological therapies would help, if they don’t a course of SSRIs would. Good luck

Nothing to worry, Do regular physical exercise and do meditation and consult doctor for better understanding of your problem and guidance.

Hi

Hi, It's due to anxiety and stress. If there has been any past negative experiences which you have not processed and overcome, you need to do that to have a healthy future healthy present. For that you need to consult and talk about things. Don't be shy. You can consult me or any psychologist and talk about it and get better. All the best.

Its very difficult to handle such things.. You can try talking out to psychiatrist or do deep breathing exercise
