Done breastfeeding

So I know it's ultimately up to me , but I just would like some reassurance. My son is 7 months now and I'd like to start giving him the bottle and be done breastfeeding . Now all I hear when I tell people that is "no, you should go till 12 months at least" welll, what if I'm just so exhausted & I already made it 7 months! How long should I go for??? He takes a bottle on his and holds it himself and everything. Yes I love the bond with him while I breastfeed but I'd just like a break & sleep, and not have to watch things I eat and drink and so forth. He's very healthy and happy but I just need to know if 7 months is okay to stop at or if I should keep going?
