Am I being unreasonable

I would find things to join flamenco, maybe join Meetup to meet like minded people.
If you are a country girl, the countryside around Newcastle is beautiful and has lovely beaches, like Longsands beach, Tynemouth.
We go to Newcastle quite often to visit Gc at Uni there and usually drive out to the beach with them.
Is it perhaps that you are renting in a built up area and your not used to that? Could you move to the edges of Newcastle nearer to countryside?
I do feel sorry for you though, I don't know that I would cope so well being taken away from my family and friends.
Hopefully, you can move back when your Dp recovers.

I came to the north east from Liverpool and found people very standoffish after the bonhomie of Liverpudlians. And I do remember the relief of bumping into someone I recognised after a year. I had young children and had just been offered a job in Liverpool when DH had been offered one up here. I had no support for childcare as DH was 1 in 3 on call and my mother was dying of breast cancer so year one was a barren waste in terms of making friends and settling in. I think people in the north east can be insular even today- people don't speak to you if you support the wrong team. You have to treat it as a joke. Find an outlet for a hobby, join a gym. If there is a support group for your partners illness perhaps go to those meetings. Sometimes you make friends when united in adversity. There is some beautiful countryside here and joining a walking group might help but you may well find yourself up to your ears in hospital appointments. Tell us a little more about yourself and some northerners might give you ideas.

I am sorry you don’t like where you are living but your partner is facing worse, give it time x

Its only been a few months ,cant you put your feelings aside for the sake of his health and wellbeing? I'm sure his family aren't deliberately crowding you just being caring about their dad .

Have you posted about this before flamenco, and things are not any better ?
Four months is not long in the grand scheme of things, has the move been beneficial for your partner ? Maybe you should talk to him about how you feel and agree to review the situation in say six months. It is hard to adjust to living in a different area without the stress of your partner's illness. In the meantime try to see things in a more positive way, there must be things you can get involved with to meet people and have an interest in your life.

You are under an enormous strain. You are coping with two of the worst things that can happen to a person at the same time. Looking after a partner who is unwell and re-locating. However, I have friends in Newcastle and I know there is a lot going on there. If you need space why not take the Metro out to the coast? Have you registered with a GP? Ask them about groups which are available to support you. You don’t say what you used to do in Bucks but you could, for example, join U3A which would be a sure fire way to meet new people. I suspect the key to your quandary is in your statement that you feel ‘taken over’ by his family. You definitely need to carve out some time for yourself and begin to make new friends. Maybe someone from Newcastle who reads your post will come to the rescue. I hope so.

Not at all! We moved to another part of the country for my husbands job years ago. We are still here but it was a nightmare for me and the kids. We were so unhappy and low. We made a point of joining local things until we found our feet.

I feel for you as you need support too as a carer. Is there anything local that you could possibly attend? Is there a local library or Facebook group where you could look for this info? ?

Is your house in Bucks still there? Could you move back? What is his prognosis?
