Brightspark I am sorry to hear that things have not gone well this year.
I really hope you will find peace this summer and a new sense of purpose in your faith.
In terms of retreats, it really depends where you are in the country and how far you are willing to travel. Here are places I have been to and enjoyed, in some cases loved! They have different programms and I would recommend the location but you would need to see if what they did suited what you need.
All Hallows Convent, Ditchingham, Suffolk, on the Norfolk border.

It looks like they also have quiet houses in Norwich as well as Ditchingham. This is an Anglican convent but the weekends and events may well attract men as well as women (although really not many men if my memory serves me right!). There is also a guest house there and you can just go and stay. You can request to have meetings with one of the sisters. There are usually formal organised retreats, which are often silent but do check what is on offer. There used to be an amazing walled garden. It is a lovely tranquil place.
www.all-hallows.org/programme.php A quick look at the programme reveals art sessions and meditations, 'Circle Dance' a kind of liturgical dance (it's a long time since I did it so read up on it before you go/if you go, so you know what to expect!), there are quiet days too.
St Mary the Virgin, Convent, Wantage, Oxfordshire.

I really don't know this place well but have been and they do offer some day events and guest house accommodation. Have a look under the section Convent Guest Wing. I believe they too are Anglican nuns.
Lee Abbey in Devon

This place gets booked up very fast so before choosing a weekend you like the look of and then finding out that it is all booked up, I would suggest emailing or calling and asking what is available. They may also have some sort of accommodation you can use for a weekend or a few days and just be there but not join an actual event.
The place is run by community not an order and people are both male and female, as are the guests.
The self-catering units are called 'Tinkerbell' (a small place) 'Lee Cabin' (for 4 people) 'Beach Chalet' (for 12 people).
If you go and stay in their accommodation and want some spiritual input ask what is available, they used to have a late evening service called 'Christ in Quiet' and they probably have a Sunday service too. They are ecumenical. It is right by the sea, beautiful and tranquil, but best to actually join a weekend, I am not sure I would exactly call it a retreat in that it is not silent but I think it might achieve the healing and restoration you may need. This is not all female but again, you could ask what they can offer that might suit you.
All the best.
