Horrible girlfriend

I’m feeling like a horrible girlfriend. Tonight I plan on sleeping at my sisters because my niece asked me too ( she’s 4) and I was really excited... But as I’m sitting here I’m just feeling like a shitty girlfriend and feel like I don’t give my boyfriend enough attention. We live together so I see him all the time except when he’s working.. I’ve been so wrapped up in both of my brothers bs they are both addicts and are currently in jail . ( i talk to them when they are able to call and I put their money on their phones so they can reach out especially since my step dads in the icu because of covid. Anyways I’m feeling like my boyfriend thinks I put more effort into them then him and I’d like to change that. I want to be more intimate with my boyfriend, I want to spend less time on our phones and more time paying attention to each other. But sometimes I feel like I have to beg for attention. I really want to fix our relationship but I’m stuck on where to start...
