Anyone can benefit from professional help. If you feel that something is missing and don't know what it is, or if you have certain issues that keep coming up again and again.

But you need one especially if you are having any kinds of suicidal thoughts. Even if you don't feel you would act on them, it's a sign that something is amiss.

I've seen both psychotherapists and psychiatrists and truly appreciated their help. No matter how I was feeling that day, I always felt lighter and calmer after speaking with them.

The fact that you're asking, maybe suggests you're ready to speak to someone. Whatever your reasons or misgivings, I encourage you to go for it.
