I know it's hard Numpty, but in life we have to keep trying and see what works and what doesn't. You shouldn't have to change to be accepted. As well, there are plenty of things to do if you are lonely, however it can be hard because you live in isolation and it is hard to change. You could try volunteering and putting your passion into a project because you do need to do something that will give you confidence and social interactions. Also, in social interactions it is always hard for others to accept somebody as they are, however please try and try to let people get to know you before they find out that you are gay because then they can find out how you are such a great person and it won't be a first impression.
Good luck,
