Thank you for writing. Although I sense your frustration, I do want to remind you that you are 30, not 90. You have time to find a career that will give you satisfaction for many decades. But you won’t find a passion unless you look for it.
I suggest you start with a career counselor. Career counselors are specially trained to help people identify talents and areas of interest that can lead to a good job. A counselor will also support you as you explore different possibilities and will help you take a look at ways you may be sabotaging yourself so you can change your approach to work.
I do suggest that you use your sessions to help you take a close look at why you have so much difficulty being around other people. That probably has a great deal to do with your discomfort in jobs.
Going from job to job hasn’t worked for you. Focus instead on getting to the root of the problem.
I wish you well.
