Get hydrated. Keep some water by bedside (in a covered container, if needed). Practice breathing exercises in bed to learn relaxation laying down. You can get your anxiety to normal range naturally with these actions.
Medication depends on what you consider to be your worst symptom, and by keeping a journal, you can find the pattern of thought that is creating this.
Best wishes.

Try taking over the counter antihistamines such as benadryl or citirizine. It will make you drowsy. Also use up your energy in order to make you feel tired during sleeping time. Have a long walk of a bit of exercise. Listen to good music, relaxation techniques are everywhere in youtube. Your gonna be ok dear!

The best recommendation for medication(s) should come from a professional medical or mental health provider. There are so many pros and cons to each type of medication and any of us telling you what works or doesn't work for us would do you a disservice. I have been on and off many anti-depressants and anti-anxiety medications and NONE of them have worked ... for me. Everybody and every body is different. The biggest problem that I have with medications is the withdrawal symptoms when changing. What was originally diagnosed for me as "anxiety" has now been changed to eight different conditions along with panic disorder, PTSD, agoraphobia and other issues. A professional can help to make sure whatever (if anything) is prescribed will be for the right conditions and symptoms for YOU. I can relate to the sleep issues because my brain keeps me awake with thoughts racing constantly. It's exhausting.
