How to quit

An

So I'm still breastfeeding and everyone has bugged me about quitting , she's already 13 months and i actually do want to quit but breastfeeding seems to be so rare that no one rly understand how hard it rly is ...she nurses to sleep which makes it even worse , she doesn't have a favorite blanket or paci, she doesnt use pacis at all anymore , I've tried but she forgot how lol. She will takes sips of milk from a sippy type cup here and there but not fully drink and if i try to give her milk when she is sleepy she will smack it and wants me to breastfeed . i didn't know it would be this hard , i formula fed my first so it wasn't so bad... Anyone on here long term breastfeed and can help me learn to quit ?
