Scared asf

I’ve been having weird symptoms for a while and doctors aren’t trying to find out what it is… for over two years I have dealt with chest pain , muscle spasm, random burning sensations everywhere , strong headaches , random pain in random areas, heart palpitations and drs can’t seem or even care to help find what’s wrong .. I have gone to the e.r various amounts of time to the point where I think the drs must think I’m crazy or just don’t take me serious at this point. I have seen my dr and he seems to not care either because he brushes it off every single time … I had a baby 3 months ago and I feel like whatever is wrong with me will not be diagnosed until it’s to late 😔
