Grunge lyrics developed as part of "Generation X malaise", reflecting that demographic's feelings of "disillusionment and uselessness". Grunge songs about love were usually about "... failed, boring, doomed or destructive relationships." (e.g., "Black" by Pearl Jam). The Alice in Chains songs "Sickman", "Junkhead", "God Smack" and "Hate to Feel" have references to heroin. Grunge lyrics tended to be more introspective and aimed to enable the listener to see into "hidden" personal issues and examine the "depravity" of the world. This approach can be seen in Mudhoney's song "Touch Me I'm Sick", which includes lyrics with "deranged imagery" which depict a "broken world and a fragmented self-image"; the song includes the lines "I feel bad, and I've felt worse" and "I won't live long and I'm full of rot". Nirvana's song "Lithium", from their 1991 album "Nevermind", is about a "... man who finds faith after his girlfriend's suicide"; it depicts "... irony and ugliness" as a way of dealing with these "dark issues".
