<human>: Can you give me a shortened version of the text?

Without too much details, yeah I can be a depressive and a downer. I am willing to change this about myself, any advice would be welcomed. However, I do feel that at times he is way too critical of me, and this has me feeling worse about myself. I am struggling to communicate this to him in a way he can understand. My SO is not very emotional and thinks primarily with logic. I am just feeling even more frustrated and down because of this after he said he refuses to be around me when I am like this. I don't feel like that is helping the situation and on, again any advice is welcomed.
<bot>: SO says I am a downer, want to change, but also SO is critical and want to communicate it logically to him.
