Will BL do ?
You're always asking for something depressing... My favorite is

Incidentally Living Together
It has smut tho and its neither a seinen or josei
It matches the other desc doe
Please please manga about suicide/sh/severe depression
No fantasy or supernatural setting
No comedy
Preferably seinen or josei
