I can't bring myself to laugh, joke or engage with anyone. so if i go to the doctors will he give me anti - depressants?

Not necessarily: It depends on why it's hard for you to engage with people have have more fun. Depression is only one reason. A good mental health evaluation will help guide what kind of treatment you might benefit from, sometimes talk therapy, sometimes medication, and sometimes both can help. The most important thing is to get a good evaluation first. Hope this answer helps.

Need eval/depression: He/she may, or may not. Most likely you will be asked about your mood, symptoms, things like sleep and appetite, current stresses, and home or life situation. Your doctor is likely to refer you to a counselor or therapist for "talk therapy, " either by itself or along with recommendations for rx. Most studies show that a combo of talk therapy and medicine together is far better than either alone.
