heres some of angst that i really enjoyed. i know you are looking for only bad endings but give these a try if you ever feel like it (2 is the only one that has bad ending)
1. my recent read, not a bad ending but i think the angst is good enough

2. a classic, i think you might have read it too but i will still recommend it

3. another good ending but the angst is top notch

sorry i js realised number 2 link is actually
https://www.mangago.zone/read-manga/10_years_where_i_loved_you_the_most/

it’s actually quite sad especially for the uke (the backstory and that one chapter w the older brother) they all just want to be happy but there’s always someone stopping them. i love that they are not toxic to each other, the seme is VERY GOOD towards the uke i love him sm. they got the happy ending they deserved, give it a read! its so so good
so im looking for a bl with a bad ending or with heart breaking angst. I cannot find any good ones with good art style or with bad endings ect. please recommend me some!
