I don't think that dealing with an identity crisis can be an easy thing to deal with, as it requires a total, hard shift of the way that you view yourself. That said, ff you have a set of values, or have interpersonal relations (friendly or sexual, doesn't matter) with people (either 'real' people or even those behind a screen) and you don't see yourself as an amorphous blob (which I'm sure you don't), then you have some sort of identity. Something else will likely come along, be it a new hobby or something to achieve, but you can use that to build on the identity you've already got
