her life and telling her husband he would never see his son again

Police claim that Sheri Shermeyer, 40, suffocated her 12-month-old son John and then shot herself

A Pennsylvania mother left a long and angry Facebook message to her husband before she suffocated her infant son and shot herself in the head in a murder-suicide the day after Christmas.

'All I can think about is leaving this world. Putting a gun in my mouth and leaving. Which is what is going to happen,' Sheri Shermeyer, 40, wrote in a 600-word Facebook posting on December 26.

The body of Shermeyer was discovered by authorities on Monday afternoon inside her Shrewsbury Township home, dead from what police believe was a self-inflicted gunshot wound.

Police say the woman also used a pillow to intentionally suffocate her 12-month-old son, who appears to have died of asphyxiation.

Shermeyer posted on Facebook that she planned to kill herself and said her husband did not deserve to have a legacy

The distressed mother posted that she was 'tired of being a single parent in a 2 parent home'

Shermeyer's scathing Facebook posting, above, has received almost 2000 comments, most wanting to be non-judgmental

The bodies of the two were discovered when police were sent to the home on a welfare check after Shermeyer, 40, appeared to post a note on her Facebook page threatening to take her own life. A friend called police.

'I always thought of myself to be a strong person. I've been through Hell and back and still had a smile. I've lost too many people; family, friends, pets, jobs etc. But as of late I don't feel so strong,' read the Facebook message.

'I have been slowly dying inside. I'm confused, just torn down, hardly ever go out in public anymore, don't socialize with people, I've become a hermit.

'I feel that the ONLY thing I have to live for is this little guy asleep in my arms right now, John. He is the only reason why I haven't blown my head off right now.

'And even now, all I can think about is leaving this world. Putting a gun in my mouth and leaving.

'Which is what is going to happen.'

Too late: Authorities were sent to Sheri's Shrewsbury Township, Pennsylvania home on a welfare check Monday afternoon

The message went on to say: 'I'm tired of being a single parent in a two parent home. I'm tired of trying to hold someone accountable for their actions or should say empty promises.

I'm tired of being told the grass is greener somewhere else, tired of crying, tired of being threatened with divorce, tired of being physically ignored, tired of being emotionally abused, tired of not being able to eat or sleep, tired of the stress, tired of the headaches, tired of it all.

I thought that love would be enough, but it's not. Love of not enough, not for you. You are not capable of having someone love you. You insist on destroying everything good. You talk about how you're the whipping post, think again. Look how I get treated. It's easy for you to lash out at me because I'm here and that is what you do, all the time.'

It also addressed the young boy's father, stating: 'You will never see your son again. You don't deserve to have a son, to have a legacy.

The pair looked happy in numerous Facebook photos but apparently were anything but according to her last message

'As of late, you are hateful, ugly and downright mean ... How about calling your son a pu**y? Or a whinny a** little bitch? Telling him that he's always going to be stuck up my a**? Call me names all you want, but leave him out of this. This is why you will never see him ever again.'

She concluded telling him to go back to the 'single life.'

'So, you can have the single life back, that you throw in my face often; since you seemed to be so happy being a stumbling drunk. You can have all the pill popping, smoking and drinking you want. You can do all that without me and John.'

'Why am I putting this on social media for all to see? Because this seems to be the only way you will listen or see it. Seems to piss you off when I put "something out there". So here it is for all to see. You're not so great a guy, you're an asshole who deserves to be alone. Good bye, good riddance, wish I never wasted these past years with you.'

'He is the only reason why I haven't blown my head off right now' the tragic mom said before doing just that, said police

Almost a thousand people responded, reacting with horror. Many insisted she not be judged.

'The pain that she must have been carrying!!!! You can 'feel' it, with each sentence that she wrote!!! Not my place to judge,' wrote one person.

'This is absolutely horrible and I agree there could have been a better way. But anyone that has ever suffered from depression will understand that your mind isn't always in the right place,' wrote another.
