What does this mean? And what should I expect?

Does this mean it will be a very depressive period relationship/love-wise? How long does this last? :(

The sixth house, represents the last personal stage in development, and is thus a critical one.The self-adjustment we undergo here determines our ability to relate to others on an equal footing and, by its success or failure, unites us with or separates us from others.

With Saturn in your sixth house you have a strong work ethic, but even though your job may be burdened with responsibilities, you know how to conserve and mete out your energy. You may have difficulties in your place of work due to standing apart, being overly critical, and demanding as much from others as you do from yourself. Your critical faculties are harsh, and you may have trouble in actually employing them. Once you turn on your analytical light, you can be relentless in your judgments. You may also have trouble assimilating experiences and making them your own. You worry too much over details, and need to grow in wisdom with regard to what's worth worrying about and what's not. A well-placed Saturn in your sixth house indicates a hardy constitution, one able to withstand most diseases. An afflicted Saturn here, however, can denote a propensity towards chronic illnesses.

Love wise I'm not sure...

Saturn is always given a heavy interpretation!  Not always true!  As I get older, I look forward with eagerness and anticipation for saturn transits!  Oh yes, saturn can cause you problems...but only if you resist!  Resistance is futile!    Saturn's job is to stablize your life in whatever area she enters.  She will make you work hard, learn patience, and cause the things you do to have lasting results.  Like all outer planets, if you have been foolish, she will let  you know!  If you need to grow and learn something, she will bring it.  Yet, when she leaves, you are a more stable, secure, and wiser person.  I can find nothing worrisome about that!

Saturn's influence into the House of Creativity (5th) means that you must learn the fundamentals before you will be successful in any creative work.  Saturn can cool off a love affair that really was bad for you anyway.   Then she will bring you an older, wiser mate who will be a true partner in life instead of a constant drain and endless aggravation.  Saturn can make you wait for children until you are mature enough to care for them.  Where and what saturn will do specifically to you can only be known through your natal chart, what sign is on the 5th H. cusp, what aspects are made to other planets/houses/asteroids.

Learn what saturn wishes to teach you!  She moves cautiously, carefully, and slowly!  It is better to learn it from Saturn than wait for Pluto!  Saturn's good friend, Pluto, will tear your life apart and tear it out at the roots, so new things can grow...so learn from Saturn, so Pluto brings only joy of change to new and different, and better, things into your life.

All "heavy" transits are only hard because we insist on hanging onto things that are wrong for us, things that keep us from growth, things that keep us from achieving our goals, things that deny us what our heart desires...so do not worry about these things...Saturn/Pluto are just stern parents causing you to save your money for a rainy day instead of fritter it away on things you don't really need.  Saturn will make you study instead of hang out at the mall.  You see?  Saturn is only there to guide you, learn her lessons so that you don't have to suffer much more later.

In my natal, Mercury, Venus, and Saturn are in my 4th house and Mars, true node, and uh-oh, Pluto in my 5th.

Does this explain my current predicament, and when will it end?
