If I'm this bad at 20 why go on?

Am I a bad person for feeling horrible because all my friends (I literally know nobody not on meds) took themselves to the doctors and got meds and i had to wait 6 years before my mum forced me to get any help...and it hasn't worked. I feel like they don't even know what it's like to have problems. Maybe it's because I'm selfish and evil. I actually have impulses to do bad things because of this. Is it because I think my problems are more important than others'?

If nobody is happy why bother?

If they are just whiny people who can't deal with minor distress, aren't I too?
