SF woes

I just wanted to have a little cry, yesterday I broke my gloves 3 times just trying to go from 15 to 16. I thought today would be better. In 2 attempts I got really lucky in getting my weapon from 17 to 18 and I was naive enough to think my luck would continue. So I tried to raise the SF my overalls from 17 to 18 too. Anyway I'm out of mesos and its SF dropped to 13. It is a sad day for this noob.
