Family relationships

I’m turning 30 this year I’m the oldest sibling and the only girl. I’ve made it a goal to spend more time with my brothers at least once a month or so, but I’m starting to feel like maybe I shouldn’t try so hard…its not reciprocated much. I also send a group text to my mom and brothers and my sister in law Sunday blessings and also Monday well wishes for the week ahead. I have 3 brothers all younger than me but the one closest to me passed away 3.5 years ago. He was my best friend. I took his passing extremely hard and I abandoned my family until the last couple of years. I guess I feel like the damage is done. I try tho to keep a connection…sometimes I feel I should give up because when I’m with them I feel that my company isn’t really wanted needed or enjoyable. I enjoy our kids being together and making memories so I continue to try to make time for all of us. But am I really making a difference?
