My dad just passed and he was my main financial support

My stomach is in knots, I am so worried about supporting myself and how to take care of all the other stuff. I’m 22 and my dad mostly supported me and my sister. I feel so unprepared. I have savings, an associates degree( but it’s more of a transfer to a 4 year thing), and a certificate in medical coding. I was planning on working on my 4 year degree and had interest in pursuing arts and stuff but now it feels like my world and possibilities are crashing down. God I don’t know if that is selfish or me. Also on top of this I’m dealing with two kittens that are in our walls and air conditioning ducts…so I don’t know just feel a mess
