Work and personal life have been very stressful and is making anxiety sky rocket. I'm having these weird feelings in my chest. Some feel like it's beating really fast, others feel like it hurts and like now it's strange burning sensation? Like heart burn or something. My therapist says I need to try and not think of the worst possible scenario (which I do a lot) but with these chest feeling. It just feels so real like something is wrong. How do I stop the chest pain and just relax for at least a little bit. I haven't been sleeping and sometimes even not eating at all. What do I do?
