I feel I don't have a good excuse to be a NEET

I see people on this subreddit say that they have some sort of crippling mental illness or physical condition. Me on the other hand, I have a bachelor's degree in Computer Science, OK mental and physical health and yet, I have been unemployed for a year and a half. My mental health has been decaying, though. Some of my former classmates have gotten good jobs. I think I picked the wrong career. This whole situation is super embarrassing. I just keep failing at everything. Getting out of neetdom looks pretty far away.
