Pocket 5s in the big blind with a short stack

[SuitedPair]

First, I want to thank everyone here. I started playing last summer and started reading this site late last year and it's been a big help (I used to limp with Q8o). I don't get a chance to play a lot, and its only for entertainment, I hope posting and discussing hands will overcome some lack of experience.

$10+1, no reads. First hand of level 4. While not the shortest stack, I'm less than 5bb after posting.
