No. I haven't graduated yet. I changed career because I didn't like it anymore but we started all together. I'm still studying but seeing them graduating makes me feel suicidal because I could be graduated too if I wasn't so stupid.
I'm a failure. That's what I am. I don't fit in society and I must be dead.
Well, are you liking this new career path you chose to study? If you are, then you've made the right choice, even though graduating with your friends would be cool, it's more important to choose a career you like more, since our jobs are what we'll be doing for most of our time.
You don't seem like a failure to me, especially considering you're in college studying, and considering that you had the balls to change your course when you decided that it wasn't for you, you're also not even 30 yet, i study with people in my class who are over 30 and will be even older once graduation comes in a few years, and some of them don't even care, because they know that when they graduate, they'll be just as much of a qualified professional as all of their younger colleagues.
People nowadays live and work until 60, 70, sometimes more, so it's ok to take a few years longer to start your career path, it's nothing to be ashamed about, you didn't do anything wrong.
I have one friend tho, that sometimes vents to me about this, he's over 30 years old, and he feels uncomfortable, about his older friends building families and progressing their careers, so i know that it must be hard for you, i know that it must be an absolute pain in the ass, and i'm very sorry.
He's still a bit positive tho, as he knows that if he followed the path he was headed to, he would be very unhappy, and now, while he has these insecurities, he's happier than he was then.
I don't know if that's the case exactly for you, it depends on how you feel about your current college course, how you feel about your current friends, etc.
btw, i also certainly don't see why you must be dead, perhaps you see no other options, i know what it's like, but with "must" it sounds like an obligation, or that you deserve it, and i'm sure that's not the case here.
