It's all good in the hood.
I usually find when my emotions start to encroach on my character then thats when I try to take a small vacation from role play in general. I have actually had my OOC mood ruin a character of mine before. There is no reason to drag your character down with your poor mood. It also relieves the need for apology threads.
On a side note, for what it's worth, I haven't seen or heard you do anything that really warrants an apology. Regardless, I hope all is well and gets better with you shortly.
