Depression Support Group
Depression is a real and debilitating condition that is often misunderstood by family and friends. Its meaning can range from a prolonged period of sadness to an actual mental illness with specific symptoms. Find and share experiences with others who are going through the same struggles.
I am sure you did not want her to commit suicide ... and I am sure she would not want you to either. I can easily assume she wants you to life your life with a good degree of happiness and peace.
Well, .. as you have found out, .. happiness coming from other than yourself can easily be lost. I hope, in time, you can find love for yourself so that you have some to give to others, then GET some from others.
I know of nothing but time to heal such grief. Meanwhile, learn about happiness and where it comes from. Lots of information on that on the Internet.
Again, my condolences.
