Is my life already over?

In about five months, I'll be 28. It's finally dawned on me how little I've accomplished. Sure, I have some accomplishments. I beat cancer at age 18 and I'm the first and so far only man in my family to earn a Bachelor's Degree. But apart from that, it's all been disappointment and failure. I failed to become a teacher, I can't keep a job for longer than a year, and my attempts at starting a writing career have all stalled out for one reason or another.
Meanwhile, I go on social media and see my old friends, classmates, and co-workers succeeding. They're buying homes when I can't even afford an apartment. They're getting married and having kids when I haven't even dated let alone had sex. They're starting their careers while mine fizzled out and I can't get a job at McDonald's. I know people who are doctors, lawyers, published authors, and professional athletes. Me? I'm just a joke. A big, fat joke. I'm starting to think this is all my life will amount to, and it pisses me off to no end. All that time (and money) going to school, trying to educate and better myself and it didn't add up to a hill of beans. Why even bother anymore? Growing up, people used to tell me I would never amount to anything. I guess they were right.

@theeviloneisyou welcome to MSF. Sorry you feel like life is in a dark place.

I used to compare others then I finally realized I am not like others. I am me and no one else can be me better than me.

If you can stop comparing yourself to others you may discover your super power. We all have one but sometimes we have to look hard.

I wrote a lot and writing is hard to break into as a business. Keep following your heart. That is a way to succeed that may not show up in things but may be the most rewarding experience of your life. @CANDC

First, it sounds like you're probably having a quarter life crisis. Comparing yourself to others never helps and I guarantee that all of those people accomplishing things aren't nearly as settled or secure as they seem. You've beaten cancer and graduated from college, so already you've shown a tremendous amount of strength, will and determination.

If you really can't find a job and aren't sure what to do, I would suggest trying contract/temporary work. It may suck, but it could give you a taste of some various types of jobs and spark an interest you didn't know you had. You could also look into doing some volunteer work, maybe something related to cancer patients since you've been through it. Sometimes when life sucks, helping other people really does help shift your perspective.

Lastly, some things I wish I knew at your age.
1. Your life really is in your hands. You control how you react to things, you can and should cut out negative people from your life, and building anything is all about taking tiny steps.
2. Being uncomfortable is a blessing. It means that something isn't right and the best way to fix that is to try new things. Meet new people, try new hobbies, try different perspectives. For me, googling
any thought or emotion that comes into my head has opened my eyes to whole new worlds.
3. Don't worry about other people. I guarantee that most people are way too wrapped up in their own lives to be hyper focused on yours, so just live and don't be afraid to fail. Failure can actually teach you way more about yourself than succeeding.
4. If all else fails, just focus on what you do have and what you love. A pet, a family member, a friend, a book, a movie, a place. Just stop and appreciate it.
