I disagree with the advice you gave for several reasons:
1) You are making an assumption that the first rav didn’t relate to his emotional state. Meiheicha teisi?
2) You neglected to mention that he should tell the second rav what transpired with the first.
3) You are assuming that his emotional state allows him to be meikil on something he was mekabel on himself. Meiheicha teisi?
4) You are assuming that had the first rav understood his emotional state, he would find room to be meikil on cholov stam. Meiheicha teisi? Maybe he holds it’s assur meikar hadin and there’s no room to be meikil.
5) You are assuming that the questioner isn’t simply trying to find a heter. Meiheicha teisi? Even if he doesn’t usually try to find the easy way out, that doesn’t mean he isn’t doing so here.
Your advice to him very much comes across as if you feel (based on situations you’ve been through, which in reality might have little to do with what he’s going through) that the first rav was wrong.
I know you didn’t actually say that, but it comes across that way.
Sitting at your computer reading his post does not qualify you or I to decide on his emotional state and opine that he needs to reask the shailah. He already asked someone in person (who might know him personally) and had the opportunity to present the shailah in more detail than a CR post.
