Telling someone you like them is hard..

I've been seeing a guy for several months now and we established to be just fwb. But the last couple of months I've my feelings have been growing for him and I really wanna tell him how I feel but too scared. But I promised myself that next time I see him I will tell him. I just want to get it off my chest. Even if he doesn't feel the same way we're still gonna continue seeing each other as fwb. Any suggestions on how I can get past my anxiety and fear? Thanks!
