About Gretchen's ass pulled depression...
I understand depression is a serious subject matter and you have to at least have a basic understanding of it to relate to something like that...
That being said, that's what it took Gretchen to become a shïtty character these last three episodes: seriously her so-called "depression" came out of nowhere with no set up whatsoever, and since then, she's been a total bummer and a boring character to watch, and her interactions with other characters is just cringeworthy and overall bad. Before that depression bullshït, she was a fine and well-developed character and capable of sustaining a toxic relationship with Jimmy and being more active than the emo-angsty crap-ass character she has become.
