Motivation to keep breastfeeding

So I’ve been trying to get my 7 month old son to take a bottle for two and a half months now. I’ve tried every tip and trick in the book, I’ve spent over $1000 on bottles and sippy cups, I have every brand known to man just sitting in my cubbord collecting dust. So I think it’s time to call it quits and give up on my dreams of having an evening to myself, or a weekend away with my husband. I need some motivation and some uplifting words because lately, breastfeeding is just making me feel trapped and depressed, but it doesn’t seem like i have any other option. I love the bond we have but I still haven’t had a moment to myself in 7 months..
