What is another word for low self-esteem? Or when a person does not appreciate or value you?
Ex: a man humiliates you, never wishes anything good for you, always brings you down like with feelings, or hopes of one day doing something in the future.
I think you are mentioning two different things in your question, although they are connected in some ways.
First, low self esteem is when a person thinks about himself or herself too much in a lowly way. And for this reason does not feel good about himself or herself.
Second, a person who does not value you or mistreats you is an unkind person with some issues. This may lead to low self esteem or it may not. It really depends. If you don't care about that person, then it probably will not both you.
Third, other words for low self esteem are: self loathing and self hatred.
This is a very interesting topic. Perhaps, the more ways where this can be described, there might be a reduction of it. The condition being described seems two- fold. When someone humiliates another, it can be referred to as "degradation," or "intimidation," or "tormenting" another. If one derives a certain enjoyment in actively demonstrating this type of behavior, the term "sadist" might be applied, but be warned of its sexual connotation. These terms would be describing when the aggressor engages in such behavior against a particular topic. In terms of examining it from the receiving end, one can be "targeted," or "victimized," or "ensnared in a web of cruelty." This might be relating to your concept of "low self esteem." When one experiences this state, they can be said to "emotionally withered," or "lacking self- worth," or, if it has progressed to a point where they are without hope, the term "silenced" may apply.
To suffer from low self-esteem is to feel 'diffident'. It's a sense of 'inferiority' that impairs your 'confidence' and affects your attitude to life.
Low self-esteem may be due to depression of some kind. You consider yourself unfit or underprepared, not equipped enough to sort and battle out things in life. In such a situation, you will be exposed to criticism, humiliation, insinuation and the like.
Low self-esteem is not 'humility'; 'humility' is a virtue, for it keeps our pride and vanity under control. Low self-esteem or 'diffidence' destroys one's personality, silently generates a sense of guilt, slowly alienates an individual from others and even from himself/herself.
