Question: I am in need of a term for the feeling or condition of having to give up some life experience or opportunity due to a conflicting obligation, especially in cases of routine sacrifice of that which is considered "fulfilling".

I say "feeling or condition" because often it is sufficient to say one feels they are in a state of being subject to some condition, e.g. "I feel trapped".

I am interested in a term that has an appropriate connotation as the inverse of guilt. In other words, I am describing the contrasting negative feelings one might have (guilt vs \_\_\_) after having prioritized either self-interests or the interests of others, particularly when having a responsibility for the other party such as in parenthood.

**Update**: I appear to have actually asked for two things here. I was hoping for a means of describing the emotional condition of being bound to this scenario, but my contextual example asked for the resulting emotions that might follow, in which case *resentment* would have been a possible candidate.

Answer: 
I believe you are looking for **self-abnegation** or **abnegation**.

> 
> *self-abnegation*: the denial of one's own interests in favour of the interests of others [*Collins*](http://www.collinsdictionary.com/dictionary/english/self-abnegation)

Here are some more details and an example from *[vocabulary.com](http://www.vocabulary.com/dictionary/abnegation)*:

> 
> The noun *abnegation* definitely has the sense of self-denial and self-sacrifice. So you wouldn't use abnegation to refer to the fact that you are giving up candy in order to eat more fruit. Instead, you would use the word if you were giving up desserts in order to donate to charity all the money you saved by not eating them for a month or two.

I think you are referring to what is generally called [sense of responsibility](http://www.thefreedictionary.com/sense+of+responsibility):

> 
> * an awareness of your obligations
