Loneliness

Hi everyone, just wondered if anyone could help me out? I'm 20 years old and have been with my partner for 3 and a half years. I live with him and his parents and while he has a good circle of friends I do not. Obviously he goes on the consoles or goes out at a weekend every now and then or to the pub with his friends and I cant help but feel so lonely at these points as if I've become dependent on him. I have a very good relationship with my family and see them nearly every day but I don't have any 'friends' so to speak whom I'd see often. I just get sad as my boyfriend goes out and he has a great time with his group of friends, rightly so, and I never get the same experience. I'm young and don't want to waste my life sitting around doing nothing but I haven't got many ways of making friends in my current situation. My boyfriend asks me if I want to go out with his friends on the odd occasion but they're all Male and I just feel so awkward. I have depression and severe anxiety so this just adds to the mix.

Any advice would be grateful, or even just reassurance! Thanks.
