Hello again Izzy - glad you feel you can come talk to us and also that you have been seeing your teacher
but sorry that you and your family are having a tough time.
I'd like to offer solutions but I wish it were all that simple ...
So instead, like Cat27 I'm going to ask some questions.
Has your brother gone to university or has he set up in his own home? Is he nearby? Like Cat I wonder if you could spend some time at his place - maybe a couple of evenings a week to get some homework done? And to talk to him, as he will completely understand your predicament.
Have you actually told your teacher EXACTLY how you feel? I just wonder, as you may not wish to be so open. I do know that there may be ways to help, maybe getting some young carer's respite, helping with extra equipment ....
Could you have your own laptop - maybe a Christmas present ready for your GCSE studies? And do you have your own room to hide away in?
Does your mum have any help? A cleaner, maybe - even a daily help to cook meals? Is there a dishwasher in the house - could there be?
Does your dad go out during the day to a club or for day care?
Has he been for some respite care - this is to give the rest of your family a break from caring?
I appreciate that your mum is a doctor - but sometimes this means that it can be even more tricky for the carer (your mum) to reach out and access the support available. So has there been an assessment of your dad's needs and a carer's assessment for your mum?
I do feel, like Cat, that your family need to have some support to help care for your dad. Your mum has so much on her plate - and you and your brothers need to be able to study and to relax.
I am writing as if you were an adult, as you have been so sensible - but I understand that you are a teenager and this is a lot to deal with.
You say you and your mum talk about everything - you are so lucky, not all families are able to talk - but I wonder if you have told her exactly how you feel? Have you let her know what you have written in this latest post? She does need to know. I appreciate that you want so much to help her, but you are her responsibility, not the other way round. I mean this kindly.
Could you chat to your brother and get him to talk to her with you - not to gang up on her but just to gently let her know that you need help and you think she needs some help too.
You have nothing to fell guilty about - I would be so proud of you as a daughter and I'm sure your mum and dad both are.
