Feeling alone 🥺😢

I feel like I’m on the verge of an emotional breakdown... lately I’ve just been feeling like I have no one in my life. I don’t have many friends so it’s mainly just me and my bf of 4 years. And although I don’t have friends I always thought at least I have him and my relationship to be my safe space and now I’m even starting to question that, so I’m really alone. I’ve been thinking about it for the past couple of days and it just makes me want to cry.. all the time and I don’t think I can hold it in any longer. I really just need some words of encouragement or positivity
