The poster that replied to you put it very nicely, listening to subliminals is like putting a bandaid over a gaping wound. I think it's okay to use subliminal stuff, but you shouldn't rely on them. You still have to be willing to put in the work and do the heavy lifting.

For what it's worth, I used subliminal meditations and sleep hypnosis meditations to aid me in moving on from an ex. They were actually extremely beneficial and helped me to get my head in the right space. I found that after a week or so of playing a sleep hypnosis while I slept, I was thinking about my ex less and less during the day, I began to realize there is plenty of joy in my life without him, etc. Overall, I just think it really helped my subconscious mind to snap out of longing for them. But as I said before, it was not my only source of healing, it just helped the process. I made sure that I was working on my subconscious mind on my own (in other words, without the aid of meditations) as well.

Hopefully what I said makes sense lol. You may want to look into such meditations if you're interested in that and can find some that appeal to you. But also make sure that throughout the day, you are working through your feelings, changing your habits and making an effort to move forward, not just letting meditations do all the work for you.
