They would be better off without me.

[WinnieMaudPeggy]

I've just driven over something that has punctured my tyre. This is the third time on the same road. Husband was zero help. He looked at it, told me to go to Costco then went back to watching the football. I don't have the spare cash to replace the tyre again. Plus last time, Costco didn't actually have the tyre I needed so it was a huge hassle as had to get someone to tow it from there.
I know my husband is angry that this has happened again. I'm not sure how I'm at fault. I didn't see the sharp black metal on the road.
This all just makes me think my father was right and I am useless.
I would be worth a whole lot more dead than alive. I'm just an inconvenience who fucks things up. The only reason I haven't just walked off into the sunset is my girls but I am so tired of constantly feeling like I have to prove my worth. Maybe I should just give up.

This doesn't sound like your fault at all. It sounds like a problem with the state of the road, if anything. I'm sorry your husband is being no help but that doesn't mean you are useless. It sounds like you care about your kids a great deal, and that is worth a huge amount.

Please seek some support in real life if you are feeling this way and are able to. Phone helplines can be very helpful if you need to speak to somebody quickly - I've used them in the past and it's all very confidential and non-judgemental.

I just know I've cost a lot of money that I don't really have. Dead, I'm worth quite a lot of money.
My husband can be brilliant but also gets so worked up about bills. It was more his reaction to it all.

My dad said I cost too much but was worth very little. This is ringing in my ears. Even though it was said 30 years ago.

Have you got anyone to speak to in real life OP? I’m assuming there is a big backstory here as I know it is frustrating when these things happen but a punctured tyre isn’t a huge issue and I’m not sure what your husband could have done anyway, I also had 4 punctured literally within weeks of each other earlier this year and it was so irritating (and expensive) but it isn’t the end of the world. I suspect there is more going on so I’d really strongly advise seeking some support in real life as well as here, I’m sorry you’re struggling.

Also, for a puncture have a ring round of local garages tomorrow, it may be able to be repaired rather than needing a completely new one and a repair is £20-30 so much cheaper x

When you say you don't have the money to replace the tyre, is that the family, or you personally? If it's you personally, have you told him that?

Your tone sounds like a combination of trauma and depression. Which means you need to seek professional help for that.

The tyre is practical. Ask for help from him.

And on the worthlessness. I am sure you know that there isn't a person in the world who is worthless. We are all made of stardust. Literally. And we are the culmination of billions of years of evolution. You are a miracle. And you probably know that about your girls, right? Since they are part of you, you are too. Your brain is just telling you lies at the moment, and that can be fixed. But going away can't.

Is this the best advice to give?

The OP is clearly struggling with mental health and may not cope well as a sole parent.

We know nothing about the partner apart from him not making a big deal out of of the punctured tyre and his suggestion to take the car to Costco to get a new tyre.
