Someone really wise told me that the people that matter won't care and the people that care, don't matter. I think that is really good advice. I know its hard, but it will get easier. Others expressed that you don't have to tell anybody, you don't owe that to anyone, and you always have to make sure what you do is best for you.
Don't let anyone bring you down. If you do get down, Lookup the song S Club 7, Bring it all back. Its a great song that will cheer you on.
I hope to get to know you better. I am glad that you post here. There are a lot of people here that can give you really good advice.
