This is not your first post where you assume a small issue will cause a catastrophic result. Is it possible that you have a tendency to “awfulize” things? I’m not asking to minimize your feelings or to avoid responding to your question, but because if you find yourself often having reactions that are disproportionate to the events, a larger issue may be how you process and cope with things.
Do you have someone you trust in your daily life that you can get a little feedback from on the subject of how you process setbacks?
