Putting a different slant on this @Strawberriesandpears
First of all, other posters are absolutely correct that many C of E Churches will welcome you very warmly, and take you into their community.
However... IME you have to really be committed in many cases. Every Church I have 'joined' in all the areas I have lived, are friendly and welcoming, but they aren't keen on people just popping in on a Sunday every few weeks. And it won't be long, before they are expecting you to start coming in half hour early (and stay half hour extra) to help with tea and coffees and biscuits and cakes. (And 'set up' the Church for visitors.)
They also expect people to help with flower-arranging, and cleaning, and also with any fetes or markets (or any events) they have.
Also they have prayer mornings and evenings, and Alpha courses, and mid week Communion (as well as a Sunday one once a month,) and mum and baby group, and Evensong, and family services etc. As well as all the Easter and Christmas ones... And they expect help with weddings and Christenings...
They try to encourage people to go on Church courses, to speak in the Church/do readings etc, and they have fairly regular trips, and 'bring and share (food) meetings' at peoples homes, and occasionally it will be your home they will want to do it at.
They also try to encourage you to visit people in the community, who may be a bit housebound, or lonely, and may need company - even if said person has expressed no interest in the Church - to try and offer company and friendship, and encourage them into the Church.
I was told one time some 9-10 years ago, to go and knock on the door of the woman at No. 10 High Street (in her mid 30s, 2 young kids, husband had left her a month ago,) to offer friendship as she may be lonely. I was like
and
and thought 'what am I gonna say? Hey there, I heard you were lonely and unhappy after your husband left, can I come in and chat about it with you?' If it were me I would tell said person calling to piss off and mind their own business.
Although I have my (Christian) faith/relationship with Jesus, I'm afraid I can't give to the Church what they want and desire... And that's me at their beck and call, helping, and giving my time and effort to the Church, and giving it 100%.
Unfortunately, I am too busy with work and family and hobbies and friends, and can only give a little to the Church, so I have had to withdraw. I now only go Easter, Christmas, Armistice, and Celebration Praise etc.. and the occasional Communion. Like about 6 times a year, when many others go (who don't go a lot...)
But I think that it's an ideal place for someone who is very lonely. So if you are very lonely as you say, and looking for friends, and company and you want to give a lot of your time, then the C of E Church is the place for you.
I mean, they are not going to expect you to do/attend every single thing I have mentioned, like, all the time, but they will ask quite a lot IME.
Best wishes @Strawberriesandpears .
