You're not a horrible person. I have found myself becoming angry in similar situations. I don't like to admit this and I was worried about myself for feeling this way. I don't drive around knocking over mailboxes with a baseball bat or anything like that but sometimes I just feel angry when people get certain opportunities that I'm struggling to get. Of course I realize that I'm just angry with myself and I do have a bad habit of being too hard on myself...

I really am happy to see people getting on with their lives. It's just that sometimes I can't help but be angry with myself for not having done the same. But I do realize that there is no real ill will towards them and I would never say anything to make them feel badly.

Anyway being 26 isn't a big deal. People are just getting married at younger ages these days but 26 is certainly not an age where you need to feel worried.
