<human>: I used to be a pretty big loner before me and my ex had gotten together, but now i think that i'm possibly scared of being alone.

I was in a relationship of 2+ years, and it went bad quick. I ended up heart broken and depressed.

Since being broken up with my ex of 2+ years i've become depressed, and i've done all the things to do to help get over it, and to move on, but none of them have made any real impacts.

Life for the most part has just become very drab, and mind dulling boring to me.

I was never able to develop any strong feelings for the next girl I dated.

I'd be with her, and i'd just think about the things i wish were different about her, and then when she was gone I would think that I missed her. But I couldn't develop any feelings for her.

Now I'm dating a new girl. I think my current GF is beautiful, and i think she's pretty great all around. However, when we're together i just focus on her imperfections, the same as I did with my previous girlfriend.

I feel like i'm just using her in a lot of ways as company.

Can you condense the text into three sentences or less?
<bot>: I have had depression for a long time. I nitpick all of my girlfriends, but when they are gone, I don't like being alone.
