Hi everyone,
I'm almost 1.5yrs into phd and I feel like I've barely gotten any data. After working on my initial project for 10-11 mths I realized that this project is highly unlikely to bear any fruit. I decided to shift focus on my 2nd project. It's been 3mths since I focused intensely on this new project and although I felt there were some progress it is moving very slowly. My preliminary data is not solid as I have yet to reproduce the data consistently.

I started having constant stress for the past few months and talking to my lab members and parents made me feel better for awhil but the stress never completely go away.. Whenever my experiment fail I go into another emotional slump. I feel very shitty, very incompetent. I don't sleep well too. Having nightmares about not graduating.
I feel like talking to my supervisor about the stress and fear of not being able to graduate but I'm not close to my supervisor and don't know what she will think of me instead.

I don't know if I'm being over anxious and over reacting to my current situation?
I want to hope that things will get better in the next few years but I'm overwhelmed with the idea of not being able to graduate.
Are there people who feel the same way? I'm scared.
