Need Some Advice - Tumblr Posts

SUCKS ASS!!!

So I recently discovered I have health anxiety and must I say it sucks ass. Every single sensation I have, I think I'm dying. I ask for reinsurance all the time but now even when someone tells me they don't feel a lump or that my eyes are fine I still don't feel fine. Sometimes I wish that it would just go away because am so tired , I just want one day were I can breath without thinking something horrible gonna happen. 

Any advice on where to post a short story? I haven't 100% finished it (I'm still thinking of expanding it) but I'm thinking of posting what I have anyway for feedback and all that, but I'm not really sure where I'd put it. It's about 20 pages in my Google docs, so I feel like even if I tried to cut it in pieces it'd be a little too long for a Tumblr post... but I don't know where else I'd put it! I've looked it up but there are so many websites (few of which I've seen before) and I really don't know where to begin.
