I hope you are able to attain the closure you need and get to the bottom of why the barrenness of this "tree" is so emotionally draining.

Lemon Tree by the Move playing in my head.

you're pruning too much.

And those weren't your lemons. You deserve it.

That season has closed probably for the best.
Leave the lemon tree alone we bloody need all the trees we can get now !
Save the planet man :)
Breath some fresh air again.

You're just going to kill the tree out of vindictive spite? Karma's a bitch, you'll find out

Very pretty and the lemon flower was sweet, but the fruit of the poor lemon tree is no longer available to eat. Oh lemon tree.

not less.

That's a little extreme isn't it? The reason your tree has not bore fruit is most likely due to lack of nutrients and/or sunlight. Go on youtube or google what citrus fruit trees need. They're not the easiest thing to take care of and expect to grow fruit in this climate.

When life gives you a lemon tree, exploit the shit out of it. When it stops producing, raze it and pave a parking lot.
Yup, someone said that.
