It is all so recent for you . You may feel like your body and self have been torn but that is to be expected . What helps me get through days missing my dad is imagining what he would say to me if he saw me sad for him . What do you think your mom would say if she knew you were hurting . Shed want you to keep living and wouldnt want this to shut you down . It wont . It is now part of your story and who you are . If you can talk to other family or friends make sure you do . That is where the healing begins . They touched many lives and know you are not alone . Strangers here do feel for you . My heart ached reading your post but if you were here I would ask you to tell me all about your mom and sister . Who they were , what they liked . Talking about them helps a lot . Very sorry .
