Exactly you have choices as to what to do about certain situations but depression itself is not a choice. I'm sure we don't like feeling sad and would rather feel happy. I don't think people just make it a choice to be sad. Something's going on inside to make the sadness feeling.
Seeking help..ie therapy is making a choice to do something about depression. This comment that was made hit a nerve with me. I spent my whole life suppresing my emotions and shutting down because of stupid comments like this. I faked being happy and smiling even though I was miserable inside. I went through horrible experiences...when I had no choices. I chose to shut myself down and pretend to be someone i was not. Now I'm learning to honor ALL my feelings in order to achieve feeling happiness. There are ways of expressing ourselves appropriately. This person is supposed to be a proffesional. Anybody can say whatever they want and express their opinion but this person should not have said this in my opinion.
You deserve a place in life just like all of us do. What your feeling now is not going to last forever if you work through it. Please know there is hope. I relate to your words of questioning your existence because I still question mine sometimes but thankfully I have a good therapist. I have no family as i aged out of foster care and friends were unable to understand me. That's why i sought therapy. Because i had nobody to tell me, hey what you're feeling is normal for what you've gone through. I've learned that life can be whole and that there is hope for achieving happiness but i have to work through the things that keep me from this. I have to break old beliefs. I almost feel like i just have to re-learn everything because the life I've known is not how life is. This is where choice comes in. I just don't understand this comment, it sounds cruel to me. And unfair. I do not know what your situation is, all i can say is please don't let this hinder your journey. You are important, you matter and you deserve to be happy.
p.s.
I'm sorry if i sound like a jerk. I think i was triggered severely by this. My therapist once told me that the rule of therapy is to "do no harm." It took a lot for me to get help and i can't even imagine what would've happened if this comment would've been directed at me. I feel sad for the poster because i know what it feels like to be invalidated.
