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. In fact, therapy is for people who have enough self-awareness to realize they need a helping hand. That is something to be admired.
You are taking responsibility for yourself by accepting when you're at in life and making a commitment to change the situation by seeking therapy. Therapy provides long-lasting benefits and support, giving you the tools you need to avoid triggers, re-direct damaging patterns, and overcome whatever challenges you.
