Talking with someone who is in a position to hear your story and not make assumptions based on foreknowledge is a tremendous resource. You are free to bare your soul in a safe environment. Talking about the things that trouble you can make you feel so much better, especially when you have developed a sense of trust with the therapist. Clients have reported they are able to think clearer after sessions and therefore are able to make better decisions about their life.
Most people don't go to their medical doctor if they are not ill. Likewise, if you are not experiencing mental stress that impairs your ability to function, you may not need to see a therapist. When people can't put their finger on a pain that won't go away, they go to their medical doctor. Likewise, if you find your self struggling from time to time just to do normal day-to-day stuff, your might benefit from a conversation with a therapist. Also, you may not always be able to recognize that you have moved away from your normal, and those close to you will see that you are "not your self".
Medication (prescribed by a psychiatrist or medical doctor), is used to manage symptoms associated with a diagnosis. If you take medication to help you, it would be beneficial for you to take it a step further and see a therapist. The two together can make a world of difference in outcomes of your over-all well-being.
If you have insurance, you should call them and get clarity about your coverage for mental health services. I provide out-of-network services because I am not taking insurance at this time. You can file your sessions with your insurance for reimbursement.
Some people reach their goal in only a few sessions. Others need more time because the severity of the issue is greater. Clients experiencing a major crisis will need weekly sessions until it is feasible to attend sessions 2 or 3 times a month. Some require ongoing therapy for balance. An ideal mindset is not to wonder about how long it will last, but to focus on doing everything you can to reach your goal for good mental health and stability. When you are done, you are done. You might then only need to check in every now and then.
