Suggest Treatment For Persistent Nausea And Anxiety

am a 23 year old female, average weight. I went to bed and had not fallen asleep, then suddenly experienced bad nausea, no vomiting though. Now I m experiencing a very slight tightness in my chest, but no pain or squeezing, more like a panic type feeling. I ve also had very sporadic pains behind the breast. I have been experiencing an excessive amount of anxiety and stress the past month or so and have had anxiety issues most of my life. I just want to n make sure this is likely not a heart attack. Since the symptoms can be so many other things it s hard to tell.
