It absolutely can be. Breakups are actually what influence a lot of my clients to come to counseling for and people find it very beneficial in helping cope with all the feelings after a break up.

Therapy is effective after any significant life event

Therapy can provide a safe place to explore your pain from the breakup while learning how to effectively cope with difficult emotions.

While there isn’t a perfect way to handle breakups, psychotherapy can help. Therapy can provide a place to explore your pain from the breakup while developing coping strategies for the future. A therapist can help you better define your goals and clarify who you are and what you want out of life. A mental health professional not only listens, but provides a neutral perspective that those in your circle (friends, family members, etc.) may not be able to offer. In addition, therapy can often help promote better self-esteem as you begin to rebuild and move forward.
