If you don't know your direction, you will always be anxious.

It seems that you still have some sales talent, which depends not only on luck, but also on people's attitude and speaking skills. Don't be so insecure. Find a direction, do it, and there will be a future. Remember, when applying, don't tell others that you graduated from computer science, passed Band 4, and have a primary accounting certificate. People will think that you are uncertain and live at a loss. Do a personality test, or ask the leading colleagues around you to fully understand themselves. Hold on. . .
