What do you do when you're emotionally drained by a problem, yet you need to carry on with life?

I’m just seriously hurt by and pissed off with someone right now, it’s affecting my work, my friends, my interactions and my preparations for the upcoming examinations.

I know that logically I need to focus, but it’s hard to focus when you’re seething inside. I’m not going to go into details here, but without saying too much, it’s a seriously complicated situation where both parties have discussed the problem in depth and are also already bogged down with the rest of life.

I tried to keep my mind away and my feelings at bay, but the problem is that I see this person every single day. It’s hard to not want to lash out and solve your problems right there and then.

This is really not doing me any bit of good, but it feels like I can’t let this thing go. I want to solve it so bad, yet I sometimes feel like I’m being pushed by the very person I want to talk to. In fact, I’ve been told repeatedly that there’s nothing else to talk about, and yet I just can’t help but feel that something’s just missing.. That something just needs to be said.. That I can’t bear the blase attitude with which this person seems to be dealing with the problem. And yet the words just don’t seem to be able to come out of my mouth when I try to talk..

I don’t even know if I’ll be able to talk about my problems in the future.. I don’t know if I’ll even be able to hold my feelings in till the future before I explode.

And I’m tired… I’m so tired of this mess I’m in…

I guess my real question is: How do you deal with situations which are adversely affecting your life, yet which you know are very hard to solve in the immediate future?

Note: I’m not a person who is capable of packaging problems away. I find it extremely hard to put them inside a box and tell myself to deal with them later. To me, if a problem exists, it exists. I want to solve every little detail, every little problem which is there immediately.
