Hi RI. Welcome to Psych Central. I can almost feel your anxiety level by hearing your story. It sounds very disruptive. I would like to suggest an easy exercise to lower your anxiety but it seems more pervasive. Silently counting the inhale and exhale helps me relax and stop feeding the stress.

At this point I would get another diagnosis and therapy (talk and meds and other) plan and give it a try. The longer you wait the more entrenched anxiety is.

I also have read about CBT helping young people with anxiety.

To me trying any professionally diagnosed and prescribed therapy plan would be a step to finding stability, even if that was not the final approach you use.

Many people here at PC find they can share these feelings and what they are going through with the confidence that people go through similar things and can empathize. So many forums are offered as well as Chatrooms (after you have 5 posts or comments on others posts). Depression chat meets on Thursday night at 9pm EST and Anxiety Wednesday at 8PM.

You can also be an active member in other ways like supporting others in their questions, reading articles and posts http://forums.psychcentral.com that are applicable to your area of concern.

Please feel free to private message me or any of the Community Liaisons by left clicking on the name in blue to the left of their post) for questions or just to share.

For me lifestyle changes fit big in my recovery hopes.

I have to watch what I eat because foods I eat can stabilize my moods or exaggerate them. A high protein low carb diet with snacks or meals every 3-4 hours will over time reduce my swings. I also avoid alcohol and recreational drugs because those can really increase depression.

Other lifestyle changes that help me are doing yoga, exercises, mindfulness, calm music, and being active on Psych Central.
