My anxiety is going mad without a diagnose anyone have pots?

My heart rate is going crazy I felt adrenline constantly a few weeks ago but since haven't really but when I stand my heart rste goes really high and I keep having random tachycardia attacks palps my heart rate was 159 this morning for ages but then calmed but my heart rate for weeks has been going up on standing it'll be 90 sat 140 stood ect I haven't been well dizziness daily headaches ect and so I founds pots and decided I most probably have that as I fit the criteria they is two types one your bp drops on standing another your voice goes high mine is high when I stand so of course I go onto a group on Facebook full of pots people to gather information and find a lady who's bp and heart rate goes up when standing like me she was lovely and sent me a guide to pots to then find it says about adrenline cancer and how it's hard to detect ect so now I'm freaking out as I have had upper tummy pain but my blood work came back good for kidneys ect and now I've learnt there around that area !! I feel I'm going crazy with no answers I don't even know how long my heart has gone fast upon standing because I never used to check it standing until this tachycardia attack that I had I know my anxiety won't be helping but hospital have no answers and so a hypercondria like me goes looking for answers I have a ct scan on Friday for my head pains I have cardiologist on Tuesday night (private) my step dad's sister is a cardiologist nurse at our hospital so she said it isn't normal and is booking me in this week as they have fobbed me off has anyone got pots on this forum that could maybe help me understand ??

I really am feeling low and driving myself more crazy I need answers I know something is wrong and nobody has said it's anxiety but I know that's what they are thinking at hospital when I went because three doctors sneakily mentioned anxiety as a possibility but that's only cause I stupidly said I had anxiety to a nurse

Are you on any anti anxiety meds?

No
