Yes, you need a break; childbirth & childcare are very tiring.
Tired people generally are the ones hard to live with. Avoid mo yung pagsigaw mo - disrespectful to hubby and scary to your baby. Do not let resentments build up in you.
Mothers like us, we cannot/should not put a limit on what we can do.
Let us not cop out/surrender/yield to the pressures in our lives.
Madali talaga mag excuse excuse; to say: eh ganto ganyan lang focus ko sa job kasi ang anak ko ganto ganyan. IMO, you are fooling yourself to live a life of mediocrity; and a life of uninterrupted regrets. Do not do that to yourself.
Try to find a solution other than sending your kid off to the province.
Try to find a solution outside of your husband.
What you are asking from him now is major change -- yang he will share child care more, yang magkusang loob sya tumulong more -- darling, sa dami ng cuento dito -- you know by now, change is a personal decision -- Hindi nakukuha yan sa dakdak, guilt trips, threats, or palakpak.
Motherhood is not a disability. Kung magaling ka noon sa career mo, baket naman hindi ka continue to be magaling?
Imbes na resentful ka, finding excuses for not delivering your best at work. -- Baka mas productive na you get better organized; do not waste time fault-finding; do not spend time feeling sorry for yourself; and be proactive more.
You have a healthy baby, a healthy husband who is at home stuck to his IPad, you did not get a permanent health setback with your delivery/pregnancy, you have helpful In-laws. SWEETSORROW, look at your blessings, look at your glass as half-full, not half-empty.
Get rid of the negative emotions & "surrender ako" attitude. It will not change your circumstances.
Instead, challenge yourself to rise to the challenge of motherhood & becoming a better person & wife because of yor added dimension of motherhood. Kaya natin .
Pag nega ka -- bumibigat lang ang takbo ng araw mo.
Atchaka -- Hindi ba gusto mo kasakasama yang hubby mo. Pwes, be a person he will like to spend time with -- coz Kung lagi mo shout at him, Baka 1 day eh talagang may reason ka ma depress.
The primary challenge to living is to be a better person each day. Having a positive attitude & goodwill for all -- is half the effort already.
IMO, the 1st small step you can do para hindi ka bwiset is to feel good about yourself. Get a haircut, put red lipstick on, scent yourself, play your favorite songs, flirt & joke with hubby -- small things to perk you up.
Errr, pakialamera talaga ako, sorry -- change your SWEETSORROW to SWEETSWEET, something like that -- hwag "sweetiek" ha. Hehe. Take care of yourself.

more kahit grrrr ka.
