Anxiety

Does anyone know anything that helps with anxiety? My boyfriend has very high anxiety and freaks out because of it. I don’t want to break up with him because of it but if we cannot figure out away to help him not freak out. We are going to breaking up because I want kids and will not put them in harms way. There was a incident with my dad already and I should have broken up with him after that. But I’m trying to help him instead of write him off.
