My relationship

Me and my boyfriend are in absolute love but we bicker over tiny little things that mean nothing .... I know it's my fault but I can't stop it and I hate myself everyday for it .... To elaborate I've been going through anxiety and depression for 10 plus years now and I'm scared it might end things .... He's the one I love him and I want to have his children.... I'm just fucking it up and I don't know how to stop.
