First of all, I sometimes wonder about comparing our experiences and pain to each other's. On the one hand it does seem like you could say that you can compare, for example, a seemingly minor incident to an apparently much larger tragedy. And I think that this can help put things in perspective because sometimes we do catastrophise our experiences and realising that it probably isn't as bad as we think, is important.
But then everyone has their own story and we are each at our own stage of life. What is deeply important to you is important to you and how you feel is valid and can't be discredited.
From what I have seen of your posts, (and you have already written so many) you are incredibly articulate, mature and compassionate, reaching out to support people much older than yourself. I think this is an amazing strength. It probably means you are intelligent and sensitive and I think that also means you are vulnerable to difficult emotions and experiences too.
It sounds like you struggle with a strong sense of emptiness... I'm wondering if you need a bit more support than the 'feeling for you' response from your friends. It sounds like it would be good to explore things a bit more deeply. Who can you talk to about this I wonder? Parents? Other relatives?
Also, I think it might be useful to just have one thread where you write all your stuff (of course you should keep reaching out to support others in threads) and that way there won't be multiple conversations happening at the same time and people will be able to get a better sense of your whole situation. How does that sound?
