According to www.psychologytoday.com, Psychotherapy, also called talk therapy or usually just “therapy,” is a form of treatment aimed at relieving emotional distress and mental health problems. Provided by any of a variety of trained professionals— psychiatrists, psychologists, social workers, or licensed counselors—it involves examining and gaining insight into life choices and difficulties faced by individuals, couples, or families. Therapy sessions refer to structured meetings between a licensed provider and a client with a goal of improving some aspect of their life. Psychotherapy encompasses many types of treatment and is practiced by a range of clinicians using a variety of strategies. The critical aspect is that the client or patient works collaboratively with the therapist and can identify improvement and positive change over time.

The American Psychological Association suggests that it might be time to seek therapy if you have one or more issues causing you distress and interfering with your daily life.
And, if you have a mental health condition left unchecked, you could risk:
⦁ having trouble keeping relationships
⦁ finding it difficult to care for yourself or others
⦁ struggling at work or school
⦁ experiencing an increase in health issues and/or hospitalization
⦁ suicide
⦁ unstable emotions

On average, mental health problems affect one in five adults in the U.S. Mental illness does not discriminate; they can affect anyone, regardless of gender, age, income, social status, ethnicity, religion, sexual orientation or background. (NAMI)

• Helping someone realize how certain behaviors, thoughts, and other feelings or situations can worsen their mental illness. For example, some self-defeating thoughts can make your depression worse. 
• Speaking with a therapist during psychotherapy can help the person avoid these triggers or learn how to cope.  It can help people see how certain events can contribute to their mental illness. For example, if you have a new job, have someone die in the family, or have any other change, it can affect your mind and lead to situational depression or anxiety.  A psychotherapist can help you find the reasons for your problems and help you move on.
• A psychotherapist can help you control your life. They will allow you to keep a sense of pleasure or control that you haven’t experienced before.
• You can learn different techniques that can help treat your illness and your way of thinking. You can also learn life skills that can allow you to solve problems much easier.

This really is determined by you and your therapist.  If you are feeling better, you may want to consider seeing your therapist less frequently.  For example, many people start therapy on a weekly basis and then may move onto an every-other-week schedule. Eventually, meeting monthly may work best for you.
