Anyway I have been through what you are going through and even suffer from it somewhat now in my old age.
Let's list what has happened:
A devastating break up
Not being able to earn enough to live out on your own at 24
Shutting out friends, feeling that you drag them down
All 3 of those are common by themselves but when combined, they just multiply the depression.  What if you could work on each one, one at a time at first, and then 2 or 3 at a time?
First I would connect with just 2 or 3 good friends.  You don't have to unload a lot of vaguely depressing stuff.  Just say 'take me with you places, even though I am not over my relationship, and prop me in a corner, and don't try to cheer me up or act artificial.'  Getting out a couple of times a week will start to help.
Later, sit down with a notebook and track all your income and expenses.  See if there are ways you can save X dollars per paycheck, which you should be able to do when you are living at home.  Then slowly start asking around for people who might want to get an apartment together to save on expenses.  When I was young, I did that for the first 15 years away from home.  It was a meager existence, but it can be done.
Life doesn't really have any meaning other than what you make of it, if you are feeling let down by not having a reason for living.  Maybe you will never know your value as a human being, even if you help a turtle cross a highway or comfort a child who grows up to save the world.
