hi Mulan

I am sorry that you are depressed. Your family members may have had a different form of depression which is episodic. Yours may be chronic, which goes on all of the pain. the same as mine. Are you in therapy? That can give really good skills for managing depression. I think explaining to your family that your depression is continuous will let them know why meds are still necessary.
You are managing so far with your studies. so continuing with them is the best way to go, and if there are difficulties in the future you can always get help from the Dr. or a therapist.
There is Nami the organization for the mentally ill which you can Google, and contact to find out what services they have in your area. Very often they do have. peer to peer support groups where you can make good trustworthy friends and fellow sufferers make the best ones. There may also be depression support groups in your area that would be helpful. I hope and pray everything gets better for you soon. Take care. God bless and best wishes from your friend Francis
