Thyroid, SMA panels: Your doctor will probably also want to order thyroid and metabolic panels. However, it's possible none of these labs will show anything abnormal . . . . In situations like yours, they often don't. You do need a history and physical, etc, though. You may also benefit from consulting with a psychiatrist or psychologist for help with social anxiety and stress.

Speak with your Md: Anxiety and stress are very common in our fast paced lives. There could be many causes, but start by speaking with your general practitioner. Explain to her/him in as much detail as it will help. You are a young man, but cortisol levels could be decreased. You could request them, but the test requires a different visit usually. Start with a check up, CBC with differential, cholesterol.
