Does depression involve temporary or permament sociopathy?

Note: I don't ask you for "additional help". Don't send me links, helps or anything. Anything but the question will be ignored, don't waste your time.

So, 2 years ago, I hit state of something I thought was just unslept hours which hit me for longer time. I gradientally got myself into state that could be called depression, but also sociopathy.

Sociopath people aren't capable for feeling emotions for others, hell, I don't even feel my own emotions. Now I'm 17 (8/10) years, I've been through this thing ever since my 15th year (so about two years now). Before this happening, I was like human version of dog, I was happy, cheering, ugly as... buldozer, always willing to help. Now I'm just ugly and willing to help.

If got rid of depression. Would "sociopathy" effect fade away, or it will be scar that will remain and haunt me my entire life? Or, I would stay like this no matter what?

If I get rid of depression. Would I be as happy as before it, if I really tried really hard? I really miss those days man,  .

Once again, I don't need any links, just answer the question if you're willing to and know how to.
