I also did not have any friends my entire childhood. I used to sit alone in class, hoping for the day to be over. At home, I used to sit alone in a shut room. I survived school without any problems. But in college, my depression started getting worse. My faculty members were always rude and very strict. I started to isolate myself and stopped going to college entirely. I would sit alone in my room locked from the inside and curtains drawn. My parents didn't know as I was in another city and when they did know, they only screamed at me, making me even more depressed. My depression started getting worse and it started affecting my mental faculties. I felt like I was getting more and more blunt and dumb. Isolating did not help at all. As now, I have to finish all the remaining credits and my life is harder than ever. The depression is killing me from the inside. I have started working and first few days, I was avoiding my boss. Oh boy, was it a bad idea?!

Now, I am just struggling to some day finish my degree and get a permanent job. My social anxiety, loneliness, etc. may not go away, but at least there will be peace, calm, monotony and a paycheck.

So to all people here, I understand things are hard. But, don't let things go way out of hand. Don't isolate yourself as it will not solve any problems. Most of the challenges will remain. Even if you are avoidant, don't let things get worse. If you are avoidant and also depressed, don't think how can things get any worse. Because believe me, things can get a lot worse. A lot of people have depression, but there are varying degrees of depression. I have had depression for around 10 years. But now it seems to be more extreme. It's like now I have Depression+
