severe depression ?

I'm 100 percent sure I have a major depressive disorder . At this point it's hard for me to even attend work . I barely go and will probably be fired . My relationships with my SO and family are not in the best place . I finished school and was never able to find a job and I feel guilty about that as well . Every time I look up another friend or family member  is pregnant . I had been trying for a year but got so depressed about it I kinda lost hope then i started to feel like I'm slipping . Idk . Sometimes I think about not being here would be easier but I know people say that's not an answer to your problems . It's a lot of stuff I'm leaving out ... just venting . My chest always hurts ... I'm always in the verge of crying ... it's really frustrating. Maybe I need medication. Thanks for reading . Just needed to say that .
