Why do my realitives ways they they haven't heard from me when I talked to them two weeks ago?

Jeez. I know they love me but give me some space. Grieving on my mom even though it's been four years. My aunt called me early and asked why I haven't been calling her. She texted me, "Good morning niece. I haven't been hearing from you in a while. You okay?"
I saw her like almost two weeks ago. I'm going to text her now. I'm trying to be sad but my friends and family won't let me. My other aunts never call or text me. Probably because they're busy with work and other things
