Based on your symptoms, depression is a realistic possible diagnosis. To be diagnosed with depression one does not necessarily experience deep and constant sadness. Your symptoms, that may be indicative of depression, include: feeling emotionally “flat,” withdrawn, having trouble concentrating, sleep difficulties, loss of motivation, procrastination, and feeling “down.” These are all signs of depression.
What should your next steps be? You should be evaluated by a mental health professional. The mental health professional can verify whether you have a depression diagnosis. Secondly, seek treatment. You’ve noticed a change in your mood and behavior. You don’t have to wait until your symptoms become overwhelming before you enter treatment. Ideally, an individual should seek treatment as soon as they notice a negative change in their thinking and behavior. Third, visit your primary care physician. He or she can rule out a possible medical problem. In addition, your primary care physician can prescribe psychiatric medication.
My last and most important piece of advice is to speak to your parents. Let them know about your concerns. They can help you access treatment. Keep this in mind: your parents can only help if they are aware that a problem may exist. Communicate with them as much as possible.
I hope this answer helps guide you in the right direction. I wish you the best of luck. Please take care.
