emotionally depress

Mga momsh, have you ever experience ma depress during pregnancy? I'm 26weeks pregnant pero i felt like this past few days msyado akong emotional, i feel sad sometimes the moment i wake up, iritable ako mdali akong mainis kahit sa simpleng bagay, at night it's so hard for me to sleep nggising ako lagi hnd derecho yung sleep ko. Hndi ko alam san ng gagaling pero ang dami kong worries, I feel alone wala akong masabihan, my husband is away from me and i don't think na maiintndhan nya ko, i tried to tell my mom pero ang sabi nya lang sakin "wag akong maarte" that's why i don't want to open it up. Do i need to seek a doctor? Or normal lang lahat ng nrrmdaman ko, by the way I'm a first time mom.
