Lyrics about mental illnesses

Check out the latest Blue October album - Any Man In America.
Actually any of their albums will have what you're looking for, but you said recent. This latest album does mention mental health problems but is also about father's rights.

Justin Furstenfeld, the lead singer and songwriter, is bi-polar and is very open about his problems. I went to see them last November and they were brilliantly superb!

Something like Six Degrees of Inner Turbulence?

Not all of them are strictly about mental illnesses, yet still they oscillate around that topic somehow.

A-slam - Quiet room (schizophrenia).
Covenant - Stalker (paranoia? I don't really know).
Energy Level Low - Get rid of you.
Energy Level Low - Breaker.
Energy Level Low - Pig-made hero.
A.J.K.S. - 5 CAC.
A.J.K.S. - Niekompatybilny.
Virus - Clonazepam (prescription drug addiction).
thekeenone - Legal drug addict (prescription drug addiction).
Eminem - Deja vu (prescription drug addiction).
Mind.in.a.box - Stalkers (paranoia and probably something else).
Mind.in.a.box - Between worlds.
Mind.in.a.box - Escape.
Mind.in.a.box - Machine run.
Seabound - Poisonous friend.
Seabound - Hooked (an obsession).
Seabound - Torn.
Ilya - Bpd.
MDFMK - Witch hunt (it's not about a mental illness, but about what happened to the band after they got associated with a school shooting, though the lyrics seem a bit paranoid to me anyway).
Yoav (feat. Emily Browning) - Where is my mind.
Andrew Jackson Jihad - Self esteem (some kind of anxiety).
Carissa's Wierd - Ignorant piece of shit (idk, something for sure).
Type O Negative - Haunted (depression).
Painbastard - Borderline (bpd).
My Bloody Valentine - You made me realise.

Well, there are thousands of them, just search in the internet (type "songs about [name of the illness]" in Google, lol).

Cheers, have fun.
