Just some advise I have for everyone going through a large change in life, whether it be graduating high-school/college in the next year or even just recently, moving somewhere far away, getting a new job, possibly getting married or considering it, just getting into a relationship, etc.
It's all going to be okay. I may not understand all the way what your going though, but I do understand that going through a big change in your life is going to be stressful. You're going to have all these thoughts of "what do I do now?" Or, "did I do enough here?" Or "Am I doing the right thing?", even "what do I do now?"
Even if you feel as if you didn't do enough, you did what you could with the time given. You may not have gotten along with everyone you wanted to, or for those graduating high school, maybe you didn't join all the clubs you wanted or socialize with as many people as you planned, but you did what you could in the time given.
If you question whether or not you're doing the right thing, if in a relationship or getting a job, maybe even moving, it's all normal. Nothing is supposed to really feel "right" or "normal" when you're making a big choice in life. Maybe in time, you'll realize that what you did was either the best or worst decision of your life, just know that what happens next is your choice. If you feel terrible about it for either making the mistake for the first time, or maybe for the second or third time, you can learn from the mistakes you know. It may sound childish, but learning from the past mistakes you've done really teaches you what to do in the future. Even if the choice you made was one of the best choices you've made, just know it can go down, and that's normal. Don't overstress about the fact that's it could go down, because it doesn't always go down, but when it does, remember it's normal and everyone goes through it. So, you're not alone, no matter how alone you feel.
As for the future for you highschoolers or college students, maybe people who just got fired, who knows what it will hold for you. Maybe you'll get a (or another) job and live on your own in an apartment or your own home, heck maybe even with your parents, or maybe you'll date someone and get married and live with them. Maybe you'll get a pet, or have/adopt a kid. No matter what, it'll all be okay, because that's what's supposed to happen in life. You may feel down and depressed sometimes, as if nothing can get better, but with time and change, it can get better. Life isn't a big field of opportunities. It's a rollercoaster of bad and good things. Either if those opportunities are something like a job or maybe marriage or something similar, just know that it can get better if you put the effort in to get better. You may not know what to do know, but sometime in the future, you'll know. It may be today, in two weeks, a month, a year. But in some amount of time, you'll know what to do. Its stressful, I get it. Just know that it can get better, or worse. It all depends on how you treat it. If you see it as a new opportunity in life, or as the end of something meaningful, just know that that is what life is. Things will end, opportunities will come to a close and may never come back again, relationships will either get stronger or weaker and eventually break off, you might get fired from your job, but know that everyone feels and experiences that, and you aren't alone.
I just hope that everyone that needs and reads this is feeling okay and that this just helped in the slightest. If you're feeling sick or unsure about what's going to happen, that's okay. It's how everyone feels at least once. Know that you're not alone when feeling this. Everyone has felt this at least one. It's your choice to feel better or worse about it.
(Here are some pictures of animals that I've seen to (hopefully) make you all feel better :3 )
