I'm close to giving up on writing

I doubt anyone would care about this post. But, if you do reply, well interesting, enjoy your stay.

I've been writing for years, about four or five, and after finishing the plot outline for my first novel, I feel like giving up.
I simply don't seem to have enough time in my life, I can't make a pattern to write because I get so tired and hopeless. My life is just flying past my eyes, hell, I've been on this site for more than a year now.
I don't have a plan for my mess of life, half the time I feel like I'm just floating in an empty dark void.
Writing isn't that fun anymore. I won't have enough time as I get older to continue writing, even find an agent or manage to properly submit at least a decent manuscript to the company.
I'm simply just done. There's nothing else I'm talented at, hell, I'm just a mere average writer. I don't see a reason to keep writing when I need to focus my little mental energy on jobs, economics, and college soon.
I'll probably delete this later, no one needs to hear me b*tch.

If you feel like that, maybe you should take a break from writing. Replenish your health bar, ya know? Take a long, healthy break from writing. If you want to give up altogether because you feel like it's emotionally and physically exhausting, and there's no gain to it, then go ahead. Your mental health is way more important-
But I do recommend just taking a long healthy break. You might wanna come back to it later when you have time.
_{but that's just my advice}

If writing is something you really wanna do, then you just have to keep at it. Take a break, come back in 6 months, but don't let it stress you out either. I know what it's like having a schedule that doesn't allow for writing. But then when I do get to sit down and write a paragraph, at least I can be glad I did that.
Whether it's a paragraph on the bus, or a sentence while waiting for the light on the street. There is time, though maybe not a schedule.
If it's something you care about, then don't worry about publishing, just write. You can worry about agents, and legal stuff later. Do it cause you want to. Don't make it a chore.
Also, on the "mere writer" bit, that's not entirely true, cause one thing that is true, is the power behind words. A signature on a document can change the world, a small clause in the law of a country can change everything for millions. A book can inspire a new writer, break someone's heart, or give them hope. Writing, no matter who does it, will never be done the same way by anyone else. Just how everyone's voice will always sound different form someone else, or two people are never truly identical. No persons words will ever be the same as anyone elses. And whatever you write, no matter how cliche, or well used the topic, will never be written the same way by anyone else.
(No idea if this will help, but that's what came to me.)

Whatever you do, it's ok.
If you choose to stop writing because it drains you, that's ok. Get some rest and do things that refresh you.
If you choose to stop for now with the idea of maybe picking it up again one day, that's ok.
If you choose to write sporadically, without the idea of publishing or sharing it with the world, because writing is fun and cathartic, that's ok.
If you decide that you'll push through and power on with all your ambitions at full force, that's also ok.

No choice you make now will be set in stone. If you're done for now, then that's perfectly alright! You can stop and do what's best for you.
But you also don't have an obligation to decide what's best for your future self. Your future self can take care of themselves. All you have to do now is what's healthy at this point in your life, and then see where that takes you.

if you can't write, don't. but remember that you started because you were more than decent at writing, and if you have any down time, you know where to go.
I won't force you to write, but remember this? I'm a strange INFJ writer, it's my passion and I'm going to get published even if I sign everything on my deathbed.
