>>5808089Getting laid only helps if your self-esteem is too much tied to other people, which is bad in the first place. The worst part of breakups is getting through the normal stuff, the things that became routine with the other person in your life, which have changed, and that just takes time.
If you just externalize your feelings, and try to use other people to feel better, you risk losing the ability to control your own feelings. You become dependent on your ability to get those externalizing experiences.
Ironically, being in touch with your feelings makes it easier to master them.
