I have suffered from depressive episodes before but this time round, I woke up to the noise of construction & it just jarred through my brain & after that I could not think straight & just went deeper & deeper into a depression & all kinds of noise started bothering me. Can't take music, nothing. Even extremely agitated by fridge & heating fan sound, not to talk of the construction. Can depression come back with such a trigger? Is my noise sensitivity related to or due to my depression? It is so bad that I just started my ECT today.
