"Am i being unreasonable to think churches should not be aloud to ring those damn bells for hours on end a few times a week it not very christain disturbing neighbours etc for several hours"
Yes, you are being unreasonable.
"Due to circumstances didnt have a choice on location and was unaware they would ring for several hours at a time due to anxiety and stress it drives me mad and at times feels like torture last Sunday was 5'5 hours of it non stop it over 3 hours twice a week"
Sorry to sound so harsh, but the stress and anxiety are yours and yours alone. To expect everyone else in your community to lose the sound of bells because you are anxious is not just unreasonable, surely you can see it's also extremely self-centred. Many people find pleasure in the sound of bells. Many people find comfort in the sound of bells. Many people just accept them as part of their physical landscape/soundscape akin to traffic noise. Do these people's wishes matter less than yours? Are they less important people than you?
You are in a hostel and have anxiety, there's a whole big backstory there. By choosing to focus on the church bells, you are also choosing not to focus on why you are in a hostel and why you have anxiety. They SHOULD be your focus.
Your presence in that hostel is definitely not permanent and should hopefully be short-term as you move to a more permanent home. The bells ringing is not going to change nor should you upset others by trying to change it, especially when your presence is temporary (and hopefully fleeting).
Instead, change your approach to the bells. There's two regular sessions. Regular. Predictable. Sunday 08.00 - 11.00, you could get up early and go out (I found walking quieted my mind and my worries when I had depression). Or you could wake to the sound and feel part of the community. Or you could lie there and seethe and - well, revel in how this is sooo bad for your anxiety. It's up to you. Thursday 19.00 to 22.00 you could be elsewhere. Or drowning the sound by watching TV. The "whenever they can in between" you could put yourself in their shoes and imagine their concentration on getting it right, imagine what they're practicing for, is it for the regular sessions or is there an upcoming wedding / funeral / Saint's Day for which there is a specific different peal?
I think it would do you good to think yourself out of your own head and into the heads of others. Deal with your anxiety and homelessness, the bells are neither here nor there in the overall scheme of things.
