Getting professional help is your number 1 option, why? Only a trained professional can prescribe the correct medication you may need, if any, and will be able to assess how bad is your situation.
There are a couple of things you can do by yourself in the meantime, especially now that you got a full week off work:
-Take a walk or run in a park or some place green: Nature has proven to effectively alleviate anxiety, it will give you a calm and relaxed sensation. And the exercise will liberate some serotonin, the so called happiness hormone, which means it will help you feeling a bit better. You have just been diagnosed with two disorders, you are likely feeling a bit down and confused, exercise will certainly help.
-Meditation: As mentioned in a comment above meditation can help you with your anxiety, if you like it you can even ask your therapist to make it part of your process. Sometimes meditation can help reveal the inner reason for these type of disorders.
-Try not to overthink it and keep a positive attitude, both disorders are completely treatable and curable, you will be in great shape again in little time. This is an opportunity to heal a wound that has been around for some time, an opportunity to improve and free yourself from those demons.
-Seek support: If you have someone close, a good friend, a partner, a mother or similar, try to look for support on them; it has been proven that patients who are encouraged by their loved ones heal faster and better.
I hope this works for you, I wish the best of luck in this new process. If I can be any of help please let me know and I would gladly answer.
