I believe it is very wise of you to consider therapy. Sometimes it can be difficult to know when professional help is required. You recognize there is a problem and know that assistance is necessary. You are on the right track.
I can understand the fact that you do not want to upset your mother by asking her to take you to therapy but it may be necessary. She may have fears and anxiety but the therapist will help her to see the situation more clearly. You can reassure her that you do not feel that she is to blame for your problems. It is possible that after you begin therapy the therapist could also help you to explain your position more clearly. This might help your mother to feel better. It might also be a clever way to bring her into counseling. It is not uncommon for a therapist to request regular meetings with the family members of his or her client. This is especially true when dealing with adolescents and young adults.
With regard to your father, your concern is that he will procrastinate. This may or may not be true. The only way to know is to try. If your father procrastinates, continually remind him of his agreement until he takes you to an appointment. You might be able to expedite this process by volunteering to search for therapists on your own. In addition, you could call various therapists and speak to them about your situation. They may have good advice for you regarding how to involve your parents in the counseling process.
If you are unsuccessful with the aforementioned ideas, you may also want to consider speaking to the counselor at school. School will be in session at the end of next month. If you have graduated high school (assuming you’ll be in college), you could seek help from the college counseling center. Most colleges have counseling centers on campus.
I hope you are able to receive counseling. As you recognize, the longer you wait to seek help the worse your situation may become. If you would like to begin searching for therapists, click the “find help” tab on the top of this page. Thanks for your question. I wish you well. Please take care.
