Okay, so being a fan of hiccupy sobs, or sobbing with a good amount of neck spasms, here are some videos which I found:

This one is from the Chinese YT equivalent Bilibili. I have seen many people posting their videos here. But this one particularly drew my attention because of the type of sobbing. This is a girl's reaction video to some Chinese show named Crash Slice I like the way tears fall from her eyes, and especially how her sobbing gets intense at times. There are lots of subtle neck movements to be seen here. She is sobbing throughout the entire video. At first, it is just light tears, but gradually she starts sobbing a little harder.

This video is from the same person. She is sobbing hard here, finding it hard to breathe and speaking along. Lots of waterworks. She is probably sad because of some clash happening between her parents about her partner.

Here the girl is sobbing extremely hard and mostly breathless. Neck movements can be observed as well, with a moderate amount of tears.

This is some extremely hard sobbing, she is unable to breathe and looks. I wish the lighting was better!!

Here a girl named Ruili can be seen sobbing and talking to her boyfriend. She is sad because of internet trolling. Her sobs are cute and fun to watch.

This is a hypnotic regression session by a therapist known as Aurelio Mejia. His videos are in Spanish and this is probably a Colombian girl, sobbing through her entire session. Sobbing starts at 7:35 and gradually increases.

Again a hypnotic regression session by the same Aurelio Mejia. The patient here starts to sob from 7:34. Again this entire session is in Spanish.

Another session in Spanish by Aurelio Mejia. Here the patient starts to build up from 9:38 onwards and sobs hard.

A healing session by another therapist Ery Cervantis. The first breakdown is from 24:48, then again from 1:23:31 at intervals till the end. These are not hard sobs, but softer ones. 

This is the first post from my end. Please post your inputs in this thread, and let me know if you enjoyed it. I will keep on posting more like these if I find it, and you might do the same!
