Sorry that you feel depressive. I don't know of it can help you but it helped me when a lost friend told me this: take the depressive moments as an alarm that is telling you that you need sort something out. Try yo look for it. Take your time to recover, you will see that you find good moments and you will enjoy them much more.
I don't know about the future. I try to live the present. If you are now depressive doesn't mean that you are going to suffe of depression forever. Look for help and you will be wiser to face to the future.

I hope you feel better soon.
A hug!
