Thank you for writing. Your letter shows you to be an insightful and caring person. Instead of blaming others for your situation, you are looking for ways to get back in charge of your feelings so you don’t hurt the ones you love. Good for you.
You didn’t mention if anything happened 5 months ago that could have started this. Is something bothering you more than you want to admit? If that’s the case, a few sessions with a counselor might help you get to the bottom of it and to figure out what to do to make things right again.
But if this change of mood has come on you all of a sudden with no discernable reason, the first step is a trip to your medical doctor. Your irritability and touchiness just might have a medical reason. Hypothyroidism, for example, may lead to depressed mood. Insufficient sleep is also a major cause of depression in teens.
If you are medically fine, then it’s time to see a mental health professional. What you are reporting may be the onset of a depression. Many people think that depression only shows up as sadness and being down. But in some people, irritability is the primary symptom.
The good news is that you can be treated. Medical causes can be addressed. Psychotherapy can help you learn how to manage your moods and get back in control of your life.
I wish you well.
