Is it normal i think people cry over tiny stuff sometimes have bigger issues

I have a idea that people who get upset about tiny things have much bigger problems they are not facing. When people are in a relationship that does not work they will fight about something tiny like "you did not wear the right shoes". I don't think the "shoes" are really the problem though.

The person on the other end of the computer killed themselves not because a boy online rejected her but they were using the computer to escape the real world and when they were cut off they were tossed back to reality which was something they did not want to face.

So they killed themselves. I don't think people who have major reactions to little things are really angered by something tiny. I think they found somewhere to project themselves but for some reason it did not work out and they got tossed back to reality. Yet the reality was something they do not want to face and so they must deal with the real world they really cant handle.

They say "Go to your happy place" yet if for some reason that place was disrupted you are forced to deal with the truth. The truth is not something a lot of people want to face. So they either ignore it and deny it or they escape. Now to a degree this might be helpful since they are relieving stress but at the same time its a rickety bridge since you can not escape reality forever and you have to face the music someday. Even if its not today.
