Hello David. The catechism of the Catholic Church (Paragraph 1377) teaches that Christ is fully present in the bread and fully present in the wine after consecration: “The Eucharistic presence of Christ begins at the moment of the consecration and endures as long as the Eucharistic species subsist. Christ is present whole and entire in each of the species and whole and entire in each of their parts, in such a way that the breaking of the bread does not divide Christ.” So when you receive just the host and not the wine you are still receiving the body, blood, soul, and divinity of Jesus. The host is no longer bread. Only the accidents remain. I only receive the host myself because I am a recovered alcoholic still in recovery. Everyone I know who is in recovery that is a Catholic only receives the host. You are not alone. Know that every time you receive the consecrated host you are receiving all of Jesus– body, blood, soul, and divinity. How awesome is that?!
