If you fake something for long enough, a lot of times you eventually won't have to fake it anymore.

I used to be the type of person who never talks to anyone. I would gladly choose to nod politely and then go about my business without saying a word to anyone. But I eventually realized that this was an obstacle, it was hindering my ability to achieve the things I wanted to achieve. So, I started forcing myself to talk with people even though I truly had no interest in talking with them and found it to be a chore. Over time that became who I really am and I don't have to force myself anymore nor do I find it to be a chore. I socialize now because that's the type of person I really am. I would never have become that kind of person if I hadn't faked it for long enough to make it true.

I haven't faced the issue you are facing. But it seems like a situation where such a strategy might work. Keep ignoring the feeling that tells you otherwise and act as if you believed you are loved and perhaps what you feel will be forced catch up with the way you act.

On a side note, I think it's a bit silly to set an arbitrary age below which a person's opinion is so worthless you don't even want to hear it. Wouldn't the opinion of a 23 year old who has already successfully dealt with that very same issue be far more valuable than the opinion of a 40 year old who never has? What if it's a 32 year old, but he learned the answer when he was 25? Is it ok because he is now 32 despite the fact he could have given you the very same answer 7 years ago? I think the age requirement is a bit silly.
