I know its all very hard and one needs lots of inner strength to cope with such circumstances. specially at times when one feels sick and tired. The suffering person finds many reasons to quit and lose himself in the hands of any disease.
First take a deep breathe, YOU ARE ALIVE, and you deserve to be happy, its just the first step which is difficult to take,once you take the first step towards your self empowerment the whole journey will automatically be transform into a wow experience, so easy and full of happiness. You have inner strength, you have all the tools within to attract happiness into your life, its just that some people don't know how to use those tools.

Ask yourself, do you really want to change your condition?
Do you really want to welcome happiness into your life?
If the answer is Yes, then i can assure you no one can stop you from getting and being what you want.
And if the answer is No, then no one can help you, no medicine and no Psychologist or Psychiatrist.

PS: Depression is an addiction, sometimes we cry and whine and tell others that we are not good, but at the same time we also don't want to get out of this state, we develop the habit of crying every now and then. I know this all because i had also been diagnosed with clinical depression, had a bad experience, but i thank my illness, because It made me what I am now, a healthy, positive being and a motivational writer and speaker

KEEP THE SPIRITS HIGH and cheers
