I Have Social Anxiety

I suffered with anxiety ever since I was in college, it all started when I lost my dad 9 years ago to sickle cell anaemia and it broke my heart and I didn't know who to talk to. It somehow affected my college studies like English and Maths, I wanted to pass the exams but I passed my maths but I failed loads of times with my English and everyone else passed in my class, I literally broke down and was on the brink of drinking and smoking but that didn't help me at all. It made me worse. Ever since I left college in June 2012, things started to get different like I started to work for my grandfather's friend and I was in a relationship at the time with my ex, after the 2 weeks things started to change I quitted working with my grandfathers friend cuz I was getting pressured to doing too many things for people and my relationship started to get rocky and my family became very distant from each other. My relationship ended with my ex since Last year cuz I found out the love bites on the neck and I been cheated on I felt angry and sick and felt like going into deep depression and I lost my self confidence. That's how I sort of felt like I knew that I have a social anxiety disorder and I have no alternative to get the help I need.
