lol im a sister

basically one of my family member passed away which made me realise a lot of things about life the only thing kept me going is my faith in islam. But now that i feel bit more stronger alhamdulillah but im just scared of loosing the faith because im not really in contact with my friends and have been spending a lot of my own and focusing on the things that really matter. i work with all most non muslim and some people at work may think im practicing because it gives me ease and comfort. Some days im really strong i can tolerate and keep focus and not let every thing and every one get to me other days i feel really low and and alone cause i feel so apart from my friends and everyone. but i know this is the way of life and i want to keep it that way.

How do you guys keep your faith so strong and stay positive.
