i feel very lonely all the time. I literally have only 2 friends. when i need someone i don't have anyone to rely on. whole day i am just out there with a mask on smiling and laughing with others but no one really understands me. I was in a 6 years relationship but it didn't go well even though I was out of it that vaccum is not filled. I just feel empty inside. I want someone like a romantic partner and this thought eats me whole day. how can I tackle this ? how do I feel content with myself again ?
