Why am I so emotional right now?

Your mind wants ur attention, simple. It has got some issue while running, so as machines make noise our mind gets overwhelmed or emotional. Because we are not accepting what is in front of us and constantly want to change it with the expected image of situations in our mind. Or, instead of finding solution we are stuck in reactions and stuck in something, and we are not able take a step further.

You may be thinking too much on an issue happened with you or someone else. Its not something to be felt ashamed of. Emotions are a part of human life. But if it's hurting you and you are not able to do what you should do, you should work on that. Take someone's help. A therapist can be more helpful.

A number of things can trigger periods of intense emotions, perhaps try and figure out when you started feeling lower than usual

Because some event, thought, belief or feeling unleashed your emotional state to the point you clearly noticing it.

It is very hard to answer this question without any information. Why do you think you are feeling this way right know? Has anything different happened in your life?

Check your reaction to your emotions. How are you reacting to your emotions? If you try observe your emotions objectively without resisting them, you will find yourself calmer.

It could be for a range of different reasons - situational impact, social impact, hormonal, mental, physical

It's tough to give a specific answer, but without knowing any background information or exploring your emotions deeper, I would simply say because it's totally normal and you are a human being! We all experience emotions due to hormones, stress, things and people we love and care about, changes in our lives, and for all sorts of reasons! There are ways to explore what's causing such a surge in emotions right this second, but for a simple answer, because you're a human being with emotions, the way you were meant to be. :)

It could be that you are having a very challenging day today. It's okay to cry but always try to see what good has happened today.

Because we as human beings have feelings and it's okay because those emotions marks what we have went through.
