assalaamu alaykum,
allahu akbar, (Allah is the greatest) and welcome to Islam sister.
i help out with my local branch of the new muslim project, that is in sheffield. there are branches all over the country - east london, leicester, southampton, liverpool, blackburn, manchester, leeds, sheffield and contacts in other places as well but i cant remember all of them.
all GOOD masjids (mosques) will find someone to help new muslims pray so go to them first as your local muslim community should be your first step for help and maybe they can send an imam or other elder to speak to your family?
but not all masjids are so good, some are a bit lazy in their duties and hence why there is a new muslim project in so many places so make use of them if your local muslim community cant help.
i would suggest you be prepared for the best and worst, i.e some parents are happy their kids have found peace, others are opposed, some are violently opposed and throw their kids out. my parents fell into the middle catagory and i ended up moving out to get away from all the arguing and death threats from former friends (i grew up in a very rough working class coal mining village).
so perhaps have a word with your muslim friends parents and ask them if you tell your parents and they do something stupid like kick you out will they take you in for a few days until social services can sort something out?
i would tell them though, you dont know how they are going to react and surely you want to share this beautiful gift from Allah with them? but you cant do that unless you tell them first and the longer you leave it the more they will be hurt you never told them all about it and kept it from them.
take care sister and if you need any further help from me or advice them pm my wife who is sister 'dafodil' on here.
assalaamu alaykum,
Abu Abdullah
ps...
take it steady, dont try to run before you can work. but not too steady, dont relax so much you stop learning and stop developing as a muslim.
