Hello,
Thanks for using doctor spring for posting your query.
I have gone through your question in detail and I can understand what you are going through.
Firstly I would like to appreciate the way you have asked your question. The whole picture is so elaborate in front of your eyes.
Your symptoms suggest that you could be having an Attention Deficit Hyperactivity Disorder, predominantly inattentive type with co-morbid redcurrant depressive disorder. Caffeine is a stimulant and thats why it has helped you.
The other possibility is social anxiety disorder. But it seems to be less likely.
The drugs that should suit you best are methylphenidate as a stimulant and Bupropion as an antidepressant. These drugs in combination will be activating you as well as take care of depression without issues of drowsiness.
ADHD was thought to be only childhood disorder but now its understood that the symptoms do persists in adulthood as well. There is a remarkable benefit with methylphenidate.
Being an online forum, I wont be able to prescribe you these medications, but you can discuss this with your psychiatrist who would be more than happy to help you.
Hope I am able to answer your concerns.
Wish you good health,
Please feel free to ask followup questions
Kind regards
Dr. Srikanth Reddy M.D.
