My sister passed about a week ago

She had a heart attack at 40. She was the goofiest, funniest, best big sister I could've asked for. I had to call and tell my dad the news. I've barely slept at all since she passed and I feel like every day is an appointment with grief when it hits me all over again seeing something that reminds me of her. Everything does. I lost my job yesterday because of too much Leave without pay before this happened and after. I couldn't focus on anything and told my supervisor it'd be irresponsible if I came in. I have several better paying offers from other companies, but I don't know how to get a handle on this. I haven't drank or sought out anything other than my anxiety meds. I feel like it'd be a disappointment to her memory. I've felt her presence every day. I can hear her calling me "Cole-Man" clear as a bell in my head. I fricking hate this. I just want my sister back. My dad sounds like he's in a fog every time we talk and it worries me that he'd do something, I've never worried about him doing anything like that before. This sucks.
Yall please tell the people you love how much they mean to you while they're still here. I love you all.
