Hi Droile,
Poor you. This sounds like a hellish time and it seems like you are getting very little support. Please don't feel bad about feeling bad- no one can cope alone all the time.
I feel strongly that you need to grab on firmly to the little support you've got and not let it go. What is your health visitor up to? Has she just told you that your only options are to bear it or put the kids into care? This is the message I got from your posts... Is she visiting you more often now she knows that you are feeling so awful and are in desperate need of support? She should be... Is she able to refer you on to Sure Start or any voluntary organisations? Home-Start and MAMA come to mind as potentially helpful but there may be others which run in your local area and are there to help with just your sort of situation. Please talk to the H/V again and see if she can refer you on to any that sound helpful. But if she is truly useless you can self-refer to most organisations. It may also be worth ringing Parentline Plus (0800 800 2222) to have a general chat about how you are feeling - they are very supportive- and to see if they can offer any information about possible help in your area.
What about DH? Is there any way of communicating to him how hard you are finding things at the moment? Does he have any choice about his working hours? (I don't know much about farming, I'm afraid so apologies if that is just a laughable thought) What about weekends? Is he pulling his weight with the boys? If you can talk to him and tell him how you are feeling, I think it's crucial that you do. What are his expectations like of how the housework etc is split? I appreciate that his working hours probably don't leave much time for house work but remember- neither do yours. Is he fully aware that until things get on a more even keel the house may be a bit chaotic unless he helps out? You just cannot do it all, Droile, and it's very important that he knows that and is ok with it. I would be expecting my partner to be taking leave from work if I were in this situation so that I could get some rest.
I echo completely what the others have said about getting ds2 to the childminders. If you truly think it's too much for him and/or the childminder to take then adjust him in gradually starting by leaving him for an hour or so and building up to full days as and when it's possible. It sounds like the childminder is a key person in your support network- almost the only one who is offering any practical help, in fact- and I would grab onto any time she can offer with both hands, if you can afford it. Don't worry too much about ds2- he'll be fine even if he does scream the place down.
Another thought, are you sure you have tapped every family member/friend for any sort of support they can offer? I know from other threads that you don't have much of an extended family to turn to but what about DH's family, if he has any? And your friends? Maybe one of them could take Ds2, ds1 or even both of them for an afternoon occasionally? Could a local teenager be trusted to wheel one of them in his buggy to the park to give you a couple of hours with just one?
If you ARE absolutely desperate and feel you really cannot cope a second longer then obviously you should call social services and ask about respite care. There is absolutely no shame in this. You are going through a very rough time and there is so little in the way of support there for you. Having said this, and sorry if it's blindingly obvious, please please try every other way of getting more support before you approach social services. They will not take your son/sons into care unless you convince them that there are serious risks to them staying under your care. IE that there are physical or emotional risks to them if they stay in the family home. Social services, in this context, are concerned with risks to CHILDREN not exhaustion, depression and lack of support for adults. That these two are often intimately connected is often overlooked, IME. If social services do agree to take either or both of your children into care you may find it quite difficult to get them back, at least in the short term, because, in taking them into care there is the implication that leaving them with you could have had serious consequences for them. I don't know where you live or what the ss provision is like there- some areas can offer much more support than others. But do think very very carefully and be very sure that there is no other option before you go down this route.
Sorry this is so long, Driole. I hope some of it helps. I really do have shedloads of sympathy. It's a very difficult time and I will be thinking of you and hoping it gets better.
