You're going to have to put up with some big differences between you and whoever it is you've got your eye on at this time. If you go on a date, you can expect awkward silences or jokes that go over your head, or theirs. You're just not in a very clear-headed frame of mind, and your communication is going to be affected.
Whatever you say is going to come out wrong; you might try to be funny and find your date just staring at you, or even mildly offended by whatever you said; or you might try to explain who you are in an email or a dating profile and fail miserably, because you just can't figure it out or be clear about it right now. In some way, misunderstandings are likely at this time. So what are you going to do about it? Keeping your smile plastered to your face is one route; you could just grin and bear it, and explain yourself as best you can. Or, you could just take a week or so away from the dating scene and just hang out and communicate with people who already know you well. That might be the better option, because you wouldn't want to make the wrong first impression on someone who could turn out to be very special.
