My girlfriend and I have been together for a year and before that we were friends for a year as well.

When we just became friends she was so ecstatic about life: she knew what she wanted for her future, she had a social life and she was set on her goals.

As we got closer we got into a relationship; but then I realised slowly she was getting more and more depressed. 

I asked what happened and she said that my insecurities were rubbing off on her and that she needed a two week break.

I understand that maybe I was being too negative (about my life) and overwhelming (I obviously didn't mean to do it) and it was starting to rub off on her; so I was fine with the break.

However after the break, things were still the same; in fact she got a bit worse.

She was falling back massively in school( and didn't care about it),  her goals were all in awry and her social life was diminishing.

I try to talk to her about it, but she's being very negative and resistant to picking herself back up.

I seriously don't know if I caused that drastic change in attitude but if I did 

I really didn't mean to. 

I am so sorry, I'll hate myself if I realised that I (directly or indirectly) caused all of this.

I'm young but I love her so much; she's my first love and it hurts so so much to see her like this 

Can someone please 

Please help me 

Please!

DR: Since the beginning of our Relationship my (19 male) girlfriend (18 female) has slowly been dipping into depression; I'm starting to feel it's my fault (if it is I really didn't mean to cause her depression). How can I help my girlfriend and our relationship?
