<human>: Can you give me a shortened version of the text?

It's weird. Just after some movies, it just brings out some inner depression in me or something. It just feels like there is a pit in my stomach, or a hole in my chest. It's really bothering me. I re-watched "Avatar" a little while ago and while it's one of my favorite movies I just felt like absolutely shit afterwards and it bugged me for days. 

It's happening again. My little sister convinced me to watch all the Twilight movies, and don't bother insulting me because I actually like those movies. I'm a straight guy, and I actually fairly like those movies.  I'm not one of those guys that think romantic movies are turbo-gay or anything like that. Anyways, I finished watching the third one and I get the same feeling. And again, it's really bothering me. 

If anyone else has felt similarly(not the same movies or shows, but same feelings) then I'd like to hear about it.
<bot>: Certain movies make me really depressed and feel like shit, and I don't know why and it bugs me a lot.
