SF vs FM. How to beat as SF?

[Ujarac]

So can anyone tell me exactly how I'm supposed to beat FM as SF. It's really just a huge advantage with FM and seems like I have no chance to win. If I get close to them and try to burst them they just escape and freeze me which makes me use an FM stand iframe or kfm stance iframe if I'm frozen and  close to them. So basically I end up using most if not all my iframes against FM. Also them constantly blocking my approach skills is a big pain in the ass also as I'm basically a sitting duck cause theirs no way for me to approach them. This is a really hard match up so just wondering if someone can help to figure out how to beat them.
