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: 
Sounds like you're balancing guilt vs *regret*.

Google's first definition of *regret* currently is:

> 
> a feeling of sadness, repentance, or disappointment over something that has happened or been done.
> 
> 
>
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
>
