Is it normal it's more comfortable to tell a lie *more* embarrassing?

I'm in my early 30s. I'm not embarrassed about being old but I'm embarrassed about telling people my real age. Because it makes me face the reality that I am not where I'd like to be: I have a job but it's not a "career" one, but something I have to do to make/save money so I hate it. I'm recently single, out of shape etc. What makes it worse is I currently I have no motivation to do anything about any of this. It makes me feel like a bit of a loser, and keep people at a distance

But a weird habit I've developed for the last few years though is lying about my age. But it's not a lie where I tell people I'm younger. I know full well that would be wrong and unethical. Instead, I tell them I'm 5 to 15 years older than I actually am. Doing this doesn't feel embarrassing at all. Is this normal? It sure doesn't make a lot of sense
