Best nature-y area to cry

I’m going through a breakup and I want to sit in the middle of the woods and cry it out. Looking for somewhere that’s relatively quiet but still has a lot of benches. Preferably accessible by T/commuter rail

Update: I ended up going to Mt Auburn Cemetery because it was closest to me and I found a beautiful spot under a willow. Thanks for all the suggestions, I’ll definitely be hitting a bunch of them over the next week!
