<human>: I recently had my 2nd wedding anniversary.  Nearly all of it has been spent without having sex.  As far as I can tell, this resulted from a few factors: 

1. My wife suffers from depression, and her sex drive seems naturally pretty low.  She feels she doesn't have the energy and isn't interested in trying anyway.  I was aware of this for most of our dating relationship, but we had premarital counseling and talked about expectations around sex, and going totally without was never on the table.  We were raised Christian, so we waited longer than most people would to start more than kissing while we dated.

2.  My wife is on Lexapro, which seems to totally kill any sex drive she would have left.  She has an appointment soon to talk about dosage/switching medication since her symptoms are pretty bad again now and a new medication with less sexual effects would be a real help.

3.  Because of her anxiety and depression, and her introverted nature, she rarely shares her thoughts and feelings.  She is more likely to share them when we're with another person rather than just me.  It often feels like she is trying to talk a lot to feel "normal" in social situations, but she doesn't feel obligated to put on the show anymore when it's just me.  Because of this we don't talk about sex much, and when we do she just acts exhausted.  This also results in things coming to a head when the frustration and helplessness builds up and I try to explain my need for sex, since it's not even on her radar.  I still don't really think she gets that it could become a dealbreaker for me.

I'm currently tossing everything around in my head and I need advice from professionals and people who have been in my position.  I'm starting to even include cheating in my list of options out of sheer helplessness and frustration in the situation.  I'll try to answer any questions you have.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I love my wife, but feeling trapped in a sexless marriage.  She suffers from clinical depression and doesn't get it.
