I would also add that the Saturn has been jumping off and on your sun for a while now, all the while squaring Transiting Pluto. This is happening on two angles for you.
Saturn on your IC shows me that family responsibilities might be taking toooo much out of you and leaving you feeling like you can not get out there and do what you need and want to do for you. You may also be addressing long held and instinctive belief systems that may be tying you to your nuclear home. Those of us with the sun on our IC can have a hard time cutting the chord. Perhaps, it's long held traditions and religions that are key to your family that you are now considering making a break from.
Transiting Pluto has joined some of your planetary heavies as well on your DC and is squaring your sun and transiting Saturn. In essence the cosmos have hit the Pause button for you in regards to ALL of your relationships. Family, friends, co-workers, lovers....the whole nine. Its all up for inspection. How are you treating them (or have been) and vice-versa. The 7th house is the house where we learn to define ourselves via others. For me, this all spells out that you are redefining WHO you are in the most certain terms. This means 'unlearning' early conditioning that no longer serves you and taking charge of what you want out of your relationships with everyone around you.
Basically, when the heavies are on the angles its time to take a break. Struggling against this time and trying to push forward is not adviseable and might even be adding to your deperssion. Be kind to yourself and get selfish.
It's time to get to know yourself on a much deeper and more real level.
One last note, is that when Saturn and Pluto are 'playing' there is bound to be a bit of fear involved. This is what motivates us to figure our stuff out.
