I neglected my hamster and she died

My hamster was not mine in the first place and i haven never wanted to have one before. It belonged to my brother's girlfriend and she has to go study oversea so she gave my brother her pets which are cat and hamster. My brother lived in other city and eventually gave a hamster to me and he took the cat. In my whole life i have never succeed to raise a pet. It eventually died or runaway so i have always avoided having a pet because i know how neglect i am to them. My brother can't take care both of them and he left a hamster with cage and some food to me. I felt pretty excited at first cause i think i am gonna be better this time but still, i feel like i am so sick. Now she's d dead after being with me for a few month. From starve to death. Both my parents hate pets so they never took care of it when I'm away. I go to school from 8-5 and got a part time job from 6-9 in the evening so i barely got time to take care of my hamster but still i make sure to have her food bowl and water full before leaving and since she stayed with me she barely eat any so i i give her a same amount of food every time, and in the week before she died. I was so busy with school and work cause my co-worker was sick and take a leave so i have to take her shift. And when i come to have free time when is weekend. She is dead. Food bowl and water empty. Maybe just a few hour dead. And i can't stand it. This is rhe first time that i feel like i killed it, it is my fault. If only i come to take care of her just a few hour before she would still be alive. I just. I am, i feel so guilty. I would never, ever have a pet again.
