The biggest thing NOT to do for me is dismiss my feelings, don't tell me I "shouldn't" feel a certain way, or I'm silly to! And being too harsh - I'm super sensitive, even if I sometimes try to hide it.
DO listen to me without offering too much logical solutions. Let me talk my feelings out when I want/need to. Reassure and encourage me. Connect with me on a deep level. Say cute things, and be tactile. :p
Maybe more later, enough for now.
