I've had experience with depression to the point where I had to take anti-depressants and also work half time instead of full time. The turning point for me was when I had to struggle to get out of bed in the morning, because the task of washing my face and brushing my teeth seemed overwhelming. I was also very confused and forgetful and not able to concentrate on anything. When I walked to work in the morning I was overcome with images of myself throwing myself in front of a car or from a bridge. I couldn't bare to be alive but I didn't want to die either. I started thinking, Am I going to feel this way forever? Do I HAVE to feel this way forever?
Apart from the medication, I saw a counsellor for 2 years which really helped. Because I had an eating disorder, I also went to a holistic training center where they helped me develop a more healthy attitude towards food and exercise. I had been exercising too much previously, as well as under eating intercepted with binge eating. So that was a major thing for me to change in order to feel better. Now I try to do exercise that I think is fun, in moderate doses, and not worry so much about what I eat. I am not as terrified of everything as I was before, I don't see my future as doomed anymore. I have made other changes too - like changing my career to something that will make ME happy, instead of something that might impress others. If I hadn't sought help, I don't want to think about how I'd have felt now. Perhaps I wouldn't have been alive.
It can be very hard to ask for help. It was for me. I felt, and still feel to some extent, that I am weak if I don't handle everything on my own. But what is the alternative? To keep on feeling like crap, losing good years of your life to this disorder? You mightn't believe it now, but you do deserve a good life and to feel good about yourself.
