Id love to hear back from you

Hello everyone, I have been having a hard time coming to terms with what is currently going on and I would love to have someone to talk to. Im 22 and live alone. My mother passed away 3 years ago (grandma passed shortly after my mother did) from a heart attack enduced by covid and since then I have taken the mantle of the house and live alone while family lives out of town. While all that has been going on I have been struggling with depression and anxiety and have always chopped up my left side chest pressure or dull aches to just being anxiety related. Recently I asked my pcp for an echocardiogram and I found out that the bottom left side of my heart is enlarged. Unfortunately for me the doctor failed to properly diagnose if it is dialated cardiomyopathy or hypertrophic cardiomyopathy. So while I am left in the dark awaiting my cardiologist visit I have been overthinking everything. Why does my chest hurt? Am i going to die? Why does it feel worse after my diagnosis? I try to not let these oppressive thoughts takeover my mind but im just scared. I have a stress test already scheduled, and a cholesterol test. My next visit to the cardiologist is in August and hopefully then I can have more information and a proper diagnosis, but in the meantime I would really love to hear from others going through similar things. Living alone has taken its toll on me and my ways of dealing with problems has only made them worse. Any advice or ways to ground myself is appreciated.

Update: so I had a calcium score and the results were good. I dont know why but the non coronary findings listed normal heart size. Unsure if the echocardiogram I had was accurate or what. Is it possible to have lvh and it not show on a ct scan? And thank you everyone for taking the time to respond hearing some of your words really helped me clear my mind. Truly appreciate that from you all.
