Mikafan- On the contrary, I understand perfectly what you are saying.
This seems to have been a feeling that has dogged me most of my life as well.
I think I could definately trace it back as far as my teens. Just this feeling of underlying unhappiness always.
For the most part I seem to veer between a low grumbling level of flatness (as you describe), to full blown (everything is black, cant get out of bed) depression.
I got a handle on the depression after ds, as I went on ad's for the first time, and what that did do for me was show me (probably for the first time) how I 'potentially' 'could' feel about life, that I actually could be happy.
Then I came off ads, to concieve and after I got pg felt v low again and was scared I was going to slump back into depression.
I realise noe there was a lot of underlying stuff going on with my family. I jsut seem to go along absorbing it all without even realising.
Then, when I stumbled onto this thread it dawned on me for the first time, that 'they' were probably the source of my unhappyness.
Im not saying this in a blaming way you understand, but the thing is Mikafan, I feel like had never 'actually' connected or engaged with my own life. I was too caught up in theirs. They would constantly download their unhappyness on to me.
Your childhood environment was probably very similar to mine. Chaotic, not much laughter, plenty of anger, blame shouting. You will have absorbed this as I did.
We then take it all with us into our own lives.It's like we carry their misery around with us. We keep it on our shoulders. We are their scapegoats remember, so we are also burdened with guilt and shame on top. It what we were trained for.
Since I 'un-connected' from my parents by cutting them off (albeit this may be temporary for me), I seem to have 'begun' for the first time to really connect with my 'own' family, and my 'own' life.
I even have moments of 'real' happyness and contentment and they are becoming more frequent, as the black moods become less.
I think for me, this thread, therapy and reading have been good oulets and writing feelings down (which Im not good at, been hiding from my feelings for too long now).
All I can tell you is, It's a bit like you tracing a path back to find an appreciation and understanding of who 'you' are. Because up til now you have been defined by someone else.
How you manage to do that has to be individual to you, but it can be done. I feel positively about that.
Sorry feel I am rambling, but hope this helps in some way?
