Ask yourself some questions about the situation, and give yourself honest answers.
Can I do anything about it right now?
Might I be able to do something about it when I’m better?
Could I spend some time thinking of potential temporary solutions while I wait, instead of spending that time worrying?
Is it happening now, or do I have time to come up with something?
If I think I can’t do anything about it, does worrying help the situation or make it worse?
These are sample questions. Ask yourself about specific concerns that worry you. Sometimes, the responses will require follow-up questions. Point is to end pointless worrying and start looking at the problem logically and realistically, without the emotion clouding your thinking.
