“I’ve found that it’s of some help to think of one’s moods and feelings about the world as being similar to weather.

Here are some obvious things about the weather:

It's real.
You can't change it by wishing it away.
If it's dark and rainy, it really is dark and rainy, and you can't alter it.
It might be dark and rainy for two weeks in a row.

BUT
it will be sunny one day.
It isn't under one's control when the sun comes out, but come out it will.
One day.

It really is the same with one's moods, I think. The wrong approach is to believe that they are illusions. Depression, anxiety, listlessness - these are all are real as the weather - AND EQUALLY NOT UNDER ONE'S CONTROL.
Not one's fault.

BUT
They will pass: really they will.

In the same way that one really has to accept the weather, one has to accept how one feels about life sometimes, "Today is a really crap day," is a perfectly realistic approach. It's all about finding a kind of mental umbrella. "Hey-ho, it's raining inside; it isn't my fault and there's nothing I can do about it, but sit it out. But the sun may well come out tomorrow, and when it does I shall take full advantage.”
― Stephen Fry

“I shall ever despise the man who can be gratified by the passion which he never wished to inspire, nor solicited the avowal of.”
― Jane Austen, Lady Susan

“I am tired of submitting my will to the caprices of others—of resigning my own judgement in deference to those to whom I owe no duty, and for whom I feel no respect.”
― Jane Austen, Lady Susan

“Oh, don't go to hell,” I said. “Stick around. We're just starting lunch.”
― Ernest Hemingway, The Sun Also Rises
