'Cheer up' was one, if not, the worst advice anyone have ever said to me. These two words triggered a lot of thoughts and I was berating myself for not being able to hide my feelings well enough from everyone around me.
I wanted everyone to know how I felt, but I couldn't bring myself up to tell them since I was afraid of the possible reaction I might get from them, so I just shut myself up in my room because no contact with people meant nothing could go wrong.
