Can you fix being overly sad when drunk?

Hi, I’ve been drinking for about a year now and drink every now and then. I’ve found that I’m a bit of an affectionate drunk, I love everything and everything loves me. And it’s great. But now I can go from giggling about how great everything is to crying, usually from thinking about a sad situation or feeling and it spirals from there until I start sobbing. And it’s genuine despair too. It really spoils the experience for me and I’m wondering if there’s any way to prevent it?
