Intervention: instruction to reappraise
Description: It might happen that in some situations in which you try to do something and you fail or things don't come up as you want, you could become angry, mad or irritated and feel some level of distress and discomfort. Next, please try to tell yourself that or would be preferable that the others are nice and/or fair to you, but if they are not, it does not mean that you or they are worthless human beings. It would be preferable that the others be nice and/or fair to you but if they are not, remember that it is only (very) bad), not catastrophic (the worst thing that could happen to you). It would be preferable that others are nice and/or fair to you, but if they are not, you can tolerate it, and go on enjoying life, even if it's more difficult at the beginning. (Szasz et al., 2011)
