Site wont load, nothing has changed.

I haven’t done anything to my blog wordpress wise.

I noticed a few weeks ago it was slow to load and now it doesn’t load at all. But I haven’t changed anything.

Could it be that I need to update wordpress?? I always manage to stuff something up while doing it so avoid it at all costs. Do you think updating will make it load??

ETA: I CAN get in to the admin side of things. But it doesn’t load from there either.
