I would suggest that you weigh the pros and cons of telling work and it's probably not a good place to start with disclosing your diagnosis. Disclosing to a friend and/or family member would be a better place to start.

I made the choice about being open about my diagnosis at work. It's something you can't take back after you disclose and unfortunately there is still stigma surrounding mental illness. I don't regret telling work, but it was a different circumstance because I had been committed then put on medical leave for 8 months. Being honest about the diagnosis prevented the speculation by my co-workers and I find keeping secrets an uncomfortable feeling.

As far as you being a burden to others, I doubt you feel that way when others open up and/or ask for help. Suffering in silence doesn't help anyone especially yourself.
