Mental illness in my next solar return?

[asperyogi]

Hi everyone,
this is my first post here! I really hope someone can some light on this for me. Have only been looking into Astrology for the last couple of months, so there are a lot of things I don't understand yet ... but I'm fascinated and want to learn!

So my specific question is: how important are Solar returns as opposed to transits, progressions, and all the other dozens of different predictive methods out there?

My next solar return has me extremely worried: my sun will be in the 12th house opposing Jupiter in the 6th. Looking back at previous solar returns, I have had the sun in the 12th only twice before, and both times I struggled with suicidal depression. I had one other bout with suicidal depression, and that year my solar return shows Mars in the 12th house, again opposing Jupiter in the 6th. (Jupiter is also in the 6th house in my natal chart.)

I'm kind of freaking out a bit, as each time I had to deal with mental illness it got worse, and last time I actually tried to commit suicide. This is 8 years ago and I thought I'd never have to go through that again, have been feeling quite sane ever since. I can't really imagine ever descending into those depths again being the person I am now, but this solar return chart has me wondering ...

Any ideas?

I appreciate your time, thanks everyone for reading!
