depressed

Deanna
I'm 4w6d and I'm so depressed. I've had depression for a long time (I've been put on different types of antidepressants) but I quit taking my medicine months ago and I was happy and no signs of being depressed but since I've found out I'm expecting it's back and I'm not sure how to feel. I want to be excited and happy but I just can't make myself. I feel so guilty..my family is happy and they want to talk about it and I just don't. I have no appetite to eat and can't sleep. I don't know what to do, is this normal or just me.?
