At 21, you should be embracing life with enthusiasm and passion for all its possibilities, not sinking into boredom and disillusionment. The fact that you are asking questions is a positive indication that you are ready to start making some changes. You know that there is more to life than this.
Absolutely, therapy can help. Sometimes understanding ourselves is as impossible as looking at our own face without a mirror. We need someone outside of ourselves to see clearly what’s going on and what might be helpful. Ask your doctor for names of local therapists. Do your homework. Take a look at their websites and ask around about their reputations. Then make an appointment. Trust yourself. You may need to make a few initial appointments before you find a therapist who feels right for you. You need to find someone you feel you can trust.
You made a very important first step in acknowledging the problem and writing to us here at PsychCentral. I hope you will follow through and find a therapist for yourself. You deserve it.
I wish you well.
