Hi! Good to see another Brit on here. Sorry to hear that your family are giving you such grief. There's a tendency to assume that all Brits, religious or otherwise, are a tolerant bunch (statistically we are!) but that can lead to people forgetting that there's plenty of intolerance, too. Worse would be to ignore the emotional damage that such intolerance can bring and the steps that society needs to take to support you and other people in your situation. I hope your family see sense sooner than later and you find what you're looking for.
