Hello Lynette, I'd like to help you with your question.
Anxiety can be very difficult to cope with because it feels like it takes over your life. It can affect everything from daily routine to sleep patterns. However, because anxiety is so common, there are many ways to treat it.
Seeing a psychiatrist is a good step for your daughter. Psychiatrists can prescribe mediation which can give your daughter help to cope better. Some psychiatrists also do therapy. If your daughter's psychiatrist does not do therapy, your daughter can see a Master's level or Ph.D level therapist. They do not prescribe medications but instead do therapy. You can find one through the psychiatrist she sees or she can talk with her doctor for a referral.
Anxiety can also be addressed through self help. There are numerous resources which can help you and your daughter learn more about anxiety so she can develop coping mechanisms to help her next time she feels anxious. Along with books, there are links and support groups so she can get support with others who have anxiety. Here is a list to help you get started:
On line links:
The Anxiety and Phobia Workbook by Edmund J. Bourne
When Panic Attacks: The New, Drug-Free Anxiety Therapy That Can Change Your Life by David D. Burns
The Cognitive Behavioral Workbook for Anxiety: A Step-by-Step Program by William J. Knaus EdD and Jon Carlson PsyD EdD
Coping with Anxiety: 10 Simple Ways to Relieve Anxiety, Fear & Worry by Edmund J. Bourne and Lorna Garano
Also, to help your daughter sleep, she can learn a very common technique called progressive muscle relaxation. The more she practices this technique, the easier it will be for her to relax when she needs to. Here is a link to help her learn the technique:
She can also see her family doctor to ask for a sleep aid or a medication such as Ativan, which is a medication she can take as needed that will help her relax. It will help her feel better until she can get into treatment.
I hope this has helped you,
