I hear you man. I don't know about you, but I find my partner isn't always such a help when I'm not doing so good.
He's usually the main person to suffer when I... loose the plot a little. I also find it a bit of a pain having to crawl back & say sorry especially when I don't... really feel like apologizing.
Do what you need to to get back, but try not to... harm yourself. & don't drink too* much, hangover is a right downer!
