Hey.
You know , this itp (and this forum) is like a prison ... there's always (worried) newcomers

Well , don't worry ! I was diagnosed almost a year ago.
It is not true that you will relapse ... If you go into remission , I recall there's like 15% chance of relapse in every decade(or something like that . I have am article for at least 10 years follow up supporting this) .
up to 10 years , about two thirds can withdraw from drugs (couple of articles).
given splenectomy is 50-50 , again 50 chance of having a drug free life (again I have supportive articles)
also rituximab seems to be curative in 1/3 of people (guess what ? again articles !)
I'm not sure about success rate of stem cell transplant success rate (which is really rarely used) but say that is 1/3.
to sum it up , the risk that you still have this after 10 years and after you tried everything is : (1-2/3)*(1-1/2)*(1-2/3)(1-1/3)=1/27 <4% !
and even if you do not achieve remission , there are handful of very nice drugs that will control your diesaes and will let you have your normal life !
read this three articles to see how rare is mortality of itp and how frequent is remission . these are very old articles . after these years , two other approaches (rituxan and TPO's) are added which have changed the game !

so , take a breath !
yeah , it might seem hard , but after couple of months you (like many of us ) will gain full control of your life .
by the way , since I was talking about remission (which is above 30k) , if you also consider safe range , say +10k , statistics even get better !
You'll soon learn how much is your danger zone and find that platelets aren't as necessary as you think ! in fact , our ancestors who were exposed to many wars and had to hunt , maybe needed 250k platelets to survive injuries , but in these days life , much much less than that is acceptable (based on your assertion that you have a desk job ).
take care
