Myocarditis advice

[12dr]

So after having covid 12 weeks ago which triggered myocarditis my symptoms have got worse again even tho I didn’t know that could be possible and just had covid again .I’m soo concerned about my symptoms and worried about going down the hospital as already been so many times .My gp is clueless and my consultant has just turned a blind eye to my worsening symptoms even before the second bout of covid .My heart races and pounds I’m soo breathless and chest pain my bloods are always normal even though mri showed oedema and myocarditis I just at my wits end with what to do .Any suggestions as I’m not coping
