Riding back home when I look down to find this:

Any options besides throwing it away?
2008ish Trek 7.3FX, I weigh 110kg(220lb), well within limits. I might have converted it to drops and did about 2000km of loaded touring and maybe 8000km of city riding. Doesn't seem to be an unusual amount of use to me :/ but i got it second hand so no warranty.
This is how tall i set the seat post:
there still was 6cm(2.4in) before the minimum insert mark!
Is this goodbye?
