Sorry to hear you haven't gotten the support you were after here, especially when the charity is for mental health and avenues of support.
Mental Health is no longer a topic that is being side-lined or shunned.
It affects a large amount of people, even more so in the current climate, us Gamers are not immune to Mental Health Issues.
I start my Christmas leave on the 17th and as long as I don't get further tasking I will come and find you and join you where ever you are to throw my support behind your fundraiser.
