Had a lovely day with the little one today. We went to playgroup this morning and we spend the day in Central London. Everything was fine. The way back with public transport wasn't very pleasant due the heat and we both were tired when we came back. We both slept for an hour and when I woke up at 5:50pm I felt absolutely terribly, I started crying and hyperventilating for about ten minutes and I still have heart racing and a strong pain in my chest. I just sat there and cried and cried, I feel so sorry for the LO who didn't understand what was going on. I was dizzy and felt I am now feeling a little bit better and I am in bed now, just want to relax.
Sorry for grammar mistakes, I am just very shaken and still feel a bit nauseous.
What causes Panic attacks? What's the best thing to do?
