the second Saturn return is USUALLY about graduating inwardly from a sense of responsibility that you've been carrying since age 28. It USED to be the time of retirement.
My parents said to me (age 58) when I was 28, we're not going to worry about you anymore, go live your life. Perfect example.
So, I went back to school and did fine.
YOUR HUGE effort agrees perfectly with my NL on the effort part and satisfying the Mars and Virgo rising perfectly. The planets help those that help themselves. This is a very complex subject. HOWEVER, I do not believe Saturn is going to give you a break as long as there is so much resentment present. It has been my experience, that that just won't slide.
The key, in my opinion, is not in your 2nd Saturn return which can ultimately be WONDERFUL, the key is in my book on the chapter on Scorpio. No one is tougher on themselves than those with Scorpio/Virgo combinations, and you have them both.
IMHO, EVERYTHING is totally dependent on you loosening up on yourself. Forgiving yourself.
Then, you will be easier on others; they will easier on you, etc. But, the anger of trying to even explain WHY YOU EXIST is the nasty voice of an untamed PLUTO.
You must tell it to go to hell, where it belongs.
You have a very strong Neptune also, which makes you very sensitive, caring and Piscean. IT CANNOT TAKE THE HARSHNESS that is taking place around it. thus, you are tired. NO WONDER.
Be kinder to you, you really are allowed to be, and I sincerely believe that all will work out.
Blessings to you
