Hello! That sounds like a tough spot you're in, I'm sorry to hear that :( As for your question, sometimes it's important to realize that what we assume another person is thinking or feeling might be faulty. We're not mind readers, after all :) How do you feel about perhaps talking about this with the important person? Have you considered it? There is a possibility they don't know you feel this way and interpreting their behaviour as them getting tired of your sadness. Talking about this very important issue might make things clearer in your relationship.
Whatever you decided to do in the end, good luck! :)
I've already told him (the important person) how I feel, but it seems that he doesn't understand it at all. And he told me he's getting tired of me, that's what makes me feel so lonley. Ps: thank you so much for your answer. I really appreciate it (:
Oh. That is a tougher spot than I thought. Are there any other important people in your life you could turn to? It is always sad and discouraging when someone we wish would support us is unable to do so for whatever reason. I know it's not the same, but there are many people willing to talk (including me, of course), whenever you feel extra lonely <3
