Not sure where else to post this ...
Sorry, this may ramble on a bit ...
Most of my life I've been insecure and behave badly in relationships. It's as if I need attention all the time to feel secure. I need to be told he loves me all the time or I start doubting it. If he's quiet for whatever reason I think it's because he doesn't want to be with me. I start questioning it, if he then won't discuss it - usually because he doesn't feel well - I get frustrated and then angry.
I'm aware this behaviour is appalling. I'm trying to change, but in the heat of the moment I seem to lose the plot and all rational thinking goes out of the window. To the extent that I tell him it's not worth continuing with the relationship, it's too much hard work ... Blah blah. I know, I know ... 
I also react badly when he's ill - I can't work out why, but it's almost as if I have to be worse off than him (or anyone) all the time - again centre of attention.
I hate the picture I'm painting and I don't want to be like this. I'm worried I'm bipolar or schizophrenic or something .. I feel like I'm going crazy.
I'm waiting for counselling and hope that will help.
In the meantime I wondered if anyone recognises this kind of behaviour and could give me some tips or recommend some reading that might help.
Sorry this is so long. Please don't just slag me off, I'm aware it's not ok. I'm desperately unhappy. I've suffered with depression for many many years. Just hoping for some help.
Thanks for reading.
