You could feel insecure or moody during this period, and ready to react against anything and everything. For that reason, it might not be the best time to make contact with someone new. Stick to your old friends, the tried-and-true people in your life who know you well, and who know how to handle you when you're in a mood.
New people might get the wrong impression of you, because you'll seem distant, even depressed, when you talk with them. You'll probably have a hard time focusing on the conversation if you're not in the best mood, and that's no way to start a relationship! Instead of giving someone special the wrong idea, you might be better off just waiting to contact them until you're feeling better, more yourself. When you're in a good mood, you'll be more able to focus on the present instead of the past. During this transit, you'll definitely focus on the past. If you're thinking of old lovers and feeling lonely or heartsick, it probably doesn't mean anything more than general moodiness. Those feelings will pass soon; you'll be back to your old self, and ready to meet someone new.
