Practical things to do along with subliminals to reinforce the new reality?

I've recently started listening to beauty and self image/concept subliminals at least once a day but more often than not twice a day. I would appreciate any advice on navigating this situation: I'm having some trouble with a surge of intrusive thoughts about feeling ugly, undesirable, insufficient, etc.

Now let me explain, the reason I started listening to the subliminals in the first place is because after having my kid my feelings self worth just disappeared. I felt like I wasn't attractive anymore and that no one would ever want me again. Now, those feelings didn't manifest in every day life, they would mostly just "come out" when I would get interested in a potential romantic partner or when the topic of being attractive was discussed around me. But in general, if that wasn't happening, I wouldn't really think about it I guess.

But a couple of days after starting the subliminals, multiple times during the day I just say to myself "I'm so ugly" or in conversation about any random topic I'd say like "Yeah when I was young and hot it was easier now it's not". I don't like this, I feel like I'm sabotaging myself. I wonder if it's my subconscious mind fighting the reprogramming or something. But the thing is when I catch my self saying that I try to affirm the contrary but I just get depressed 😔 I don't believe it and start feeling pathetic "Beautiful people don't have to look into the mirror every day and say they're beautiful".

I don't know, I guess I'd appreciate any practical recommendations to fight this or at least any possible explanation as to why it is happening.

Thank you so much in advance!
