There was no fee, so you're only chance is to get in by priority. You tried to spend an output which was only 2 days old and only 1BTC. Priority is calculated as age*amount, so there's going to be lots more transactions with higher priority which come before yours. So your only chance is to get lucky where a couple of quick blocks in a row flush out all the waiting transactions, or you have to wait for your inputs to get older so your priority increases sufficiently.
