There are a lot of things you can use for emotional soloing. For me it works best when I play slow and know what notes to bend which sound good. Sustain these notes well and bend them good and in the right place.

I can give you a lot more tips, but perhaps this video is also helpful ( you don't have to be a subscriber to access this one ).
