PhD Discussion Forum

I wonder I am a failure. I got two RA offers after my BSc. And few months later, I got an Mphil offer. Since then, nightmare begins. The laboratory I worked in was very competitive. My senior always completing resources in a destructive way. And my supervisor was claimed that he need medical treatment and so he go back to his home country for that. He only be in the University for four months during my Mphil study. After one year later, I was forced to quit my study because I have poor relationships with my supervisor due to my poor interpersonal relationship skill. And I was told my Mphil supervisor was kind of strange since he have some illness. Later on, I Applied for a MSc program and got admitted. But I was in severe depression and I hate all the professor due to what happen previously. I was nearly being insane then. I cannot afford to keep good relationship with my MSc supervisor due to my mental status. And I am now working as a clinical research assistant now which is totally not challenging. I still want to go back ti research field and get a PhD. Am I an failure? Am I qualified to do that? I am still on medical to treat depression.
