I'm debating whether or not to get a personal color analysis T_T!!

Lately, I've been really struggling with whether or not to get a personal color test. My friends keep telling me to do it, but when I actually look into it, I see a lot of talk about how the results can vary depending on lighting or my condition, so I feel a bit anxious about whether I can really trust them. I feel like if I get diagnosed once, I'll constantly be self-conscious when buying clothes or cosmetics, and I'm worried that getting a personal color analysis might just narrow my color choices. Plus, it's not cheap, so I keep wondering, "Will I regret paying this much money to get it?" I've read reviews saying that the same person can get completely different tone results at different shops... So, even though I want to try it just for fun, I keep hesitating because the results are ambiguous. Oh, has anyone tried a self-diagnosis of their personal color?
