Trapped

My depression doesnt get to me the way it once did but lately Ive experienced an issue Ive never dealt with before. Preface: I struggle with my sexuality and have for years but Ive come to a place in life where I dont want a romantic relationship with anyone at all. The dilemma Im facing is that I have two female friends who want date me but I dont want that with them (mostly because I just dont want a romantic relationship and not as much because of my struggle with my sexuality). Both know I have this struggle but both still seem to want me and Im getting very depressed about these friendships because they are becoming very awkward at this point and one of the girls is someone Ive known for 23 years and grew up with her. I dont have many friends (by choice) and the few I have seem to growing apart from me and it makes me feel like something is wrong with me and makes me feel very lonely and depressed. What should I do?
