Crying is a natural release, bad thoughts not so good. The following may prove helpful:
Write down all the things you are grateful for and cherish. When facing things we are not prepared for, it’s easy to forget all the good things in life. They are still there.
Get outdoors at least once in the day. Walk, sit on the back verandah, look at the sky, listen to the birds (or the rain). Reconnect with the big world, feel the earth slowly turn.
If you like music, listen to it. Doesn’t matter what, anything that calms your brain.
Try and laugh once a day - even in bad times, the world can be funny or absurd. The physical act of laughing is cheering by itself.
Most of all, live hour by hour, day by day. No what ifs. You can sear your soul by imagining things that may never happen. Deal with what is, not what might be. Planning is for later when you feel in control again. And you will.
Best wishes.
