"Gold" Terran in desperate need of help (And hugs)

Hi all, I hope this is in the right part of the forum. Here we go; 

I am currently in the gold league, where I felt relativley comfortable untill I took a break, and came back a few weeks ago. Now I'm in shambles, so frustrated and I really don't know what to do. I suck, I'm worthless and atm- at a lossrate o f almost 80%. 

I feel quite safe when it comes to building supply depots and SCV's- the macro stuff. However I crumble to harassment and aggression. I feel that every time I move out, my opponent strikes at my back, or is waiting eagerly for me. I seem to loose any direct aggression the few times I make it over to his/her base and often there's a counter atack already going on in my own base. 

 

I feel confused and insecure, as "I don't really know what it is that makes me loose". I don't feel uncomfortable against any specific race, all of them beat me equally ^^ 

 

Could you perhaps look a these replays, and give me some advice? And a /hug would be rather nice as well, as I'm really bummed out atm =/

TvT (this is by far the one is loose the most. however, most often the game is +1 hour, where I cant seem to break his defences)

But I also have huge problems where he either drops or goes banshee.
