I'm so sick and tired of either my family or my boyfriend complains that I don't spend time with one or the other. Its driving me crazy makes me just be by my damn self and don't want to be bothered. I'm trying to help my sister since she finally has a job and I'm helping her with her children during the week with no pay! Yet then I hear complaints from my boyfriend saying I don't spend time with him because I'm "always busy". When I do spend time with him my mom and my sister says I'm being selfish and don't want to help or they say smart stuff which eurks me. Nobody won't be satisfied til I just say fuck it and disappear from everyone. I'm sick of this war n the back and forth bs!! I can never have a peaceful or an ok day because of this..
