Getting yelled at; being at the receiving end of abuse; getting dumped…all examples of situations which can make us feel worthless. Being in situations which make us overly emotional is tough as all rational forms of thinking flies out the window. We end up asking questions such as:
"Why has this person done this to me?"
"Why did they say this to me?"
"What have I done to deserve this?"
Whilst the aforementioned questions are normal, they lack a sense of maturity. Whilst you can learn to stand up for yourself and assure that you are treated with utmost respect; that won't stop people from sometimes taking their own problems out on you. Everyone acts on their own accord as they project their own version of reality. It is important to realise that these things should never be taken personally..
Not anything anyone does has anything to do with you. Whilst you can emotionally react to a situation, allow yourself not to take on the emotional burden. People are self-involved, and looking out for number one they are most likely not even thinking about the fact that they were inadvertently rude to you, or they forgot to invite you to their party etc.
It comes down to being openly honest with another person to make them realise that you were upset by their actions. Communicate your expectations and why you were let down. Whilst it may seem that someone has done something for the purpose of hurting you; it becomes clear that this problem always ends up being about the person who inflicted hurt. It makes people more emotionally conscientious.
