I've not been able to cry for a very long time, and I really need to. Is there a method to induce crying and letting it all out ?

Listening to a sad song or a song that reminds you of something that makes you sad could work. Watching sad anime, shows, movies, ect

Not necessary.. You can try creative methods and letting out everything you want.. We all cry sometimes.. But if you find something else helps you better.. Go for it !

From my personal experience what hepls is something external that would make me cry,like really sad and depressing(mostly romantic in my case) movie or sad depressing song.

It sounds silly but I hardly ever cry except when I watch movies, so if I feel a build up and I need an outlet I watch a really soppy movie and have a good cry and that usually helps me.

It depends on what is blocking your ability to cry, a sad movie with a good ending would help. However, if you are into movies. Try a good book with a sad ending. I know these methods some stupid but they work for me.

in my case, crying happens quite periodically, and each time is the same pattern, a memory when i was treated unfair (from my point of view), and it felt wrong, like i've been punished by some higher forces. So a negative memory always induces crying easily. Another way is when everything is against me at one moment, and everything feels heavy and impossible. again crying. so myeah, something negative does the trick :D

I find that a good way to release pent up emotions is to lay down and listen to some music. You can also kick back, relax, and watch a movie that you can relate to or a movie that makes all those emotions come out.

Listening to sad songs is one method or watching a sad movie or television show.. Thinking about a particularly sad moment or time in your life can also help.

Just trying to talk about what your sad about might help you. I know that when I talk about what bothers me I tend to break down if that works for you you might cry I hope I could help.

Sometimes when I need a good cry I'll think of something sad that happened in my past, or I'll watch a few scenes of a sad movie or read a sad book. It can be very cathartic to have a good cry and I always feel better afterward.
