I want to start by saying that anyone who makes up stories about you, is no 'friend' at all. If it were me, I'd refer to that person as an acquaintance ... but not a 'friend'. Even if it is in jest.
I also want to say that I'm sorry to hear you are struggling at the moment and feel that you have nothing to look forward to. And as for that doctor, I would be seeking another doctor as soon as possible.
Maybe you could try some counseling support? It's a much steeper road when we try to deal with these things on our own, rather than seeking help. But, if you look at it this way, you've already sought help from here at Beyond Blue, so that's a plus.
In the meantime, we're here for you for as much and as long as you need. Take care. I'll be thinking of you. xo
