I have been a fairly cool and level headed person for the most part of my life so far but now I have been noticing an increase in anger issues. I've noticed since the last year or so that now I am always on the edge of breaking down in tears if anything goes slightly against the plan. I'm always frustrated all day and I'm also overthinking A LOT about almost everything in life to a point that I have small thoughts of getting myself into an accident to avoid the thing that I'm so anxious about. I've also been having thoughts about self hatred that I'm a burden on the family and that I can't do anything properly or take the right decisions at the right time and that I don't feel the emotions that I should, I feel like I'm totally numb at points and emotionless. I can't get myself to leave the bed because I just don't want to do anything and meet people. I don't feel like chasing my dreams to travel the world and getting a job in a big city after I graduate anymore (which used to be my biggest ambition in life up until a couple if years ago). So that has affected me in college as well and I can't get myself to study properly anymore because I just think what's the point now.

So is this just a teen thing and just a phase that would pass away or should I consult a therapist? Also, helpful suggestions and methods to cope with all of this will be appreciated. Thanks
