How do you deal with worrying constantly?

I have always worried a lot but, lately I can’t sleep or do quiet activities without worrying myself sick. When I start this I get extremley nauseous, I start having what feels like a hot flash, and my breathing gets faster. For the past month I have had to take sleeping pills every night and during the day if I start doing this I have to go to a loud place, talk to someone, or last resort drink alcohol. (So I can’t hear my own thoughts) If you experince this is there any techniques that you have done that has helped you? Any information will be greatly appreciated.
