Hello
it is a pity that you have such a difficult period now.
I know that now no advice will help reduce your suffering and depression.
The only doctor in this case is time. You just need to go through this period, and then everything will start to get better.
Also, try not to be alone during this period. The support of relatives and friends helps a lot.
A few years ago, my sister divorced and I saw how difficult it was for her. But six months later, her life improved and she became even happier than during the marriage.
