Everyone goes through challenging situations in life, and while you may have successfully navigated through other difficulties you've faced, there's nothing wrong with seeking out extra support when you need it.
Some may be going through a major life transition (unemployment, divorce, new job, etc.), or are not handling stressful circumstances well. Others may need assistance managing a range of other issues where individual, family, or couples therapy can help.
Therapists can provide support, problem-solving skills, and enhanced coping strategies for issues such as depression, anxiety, relationship troubles, and anger management. Therapists can also provide a fresh perspective on a difficult problem or point you in the direction of a solution.
