It is a decision whether to give love or not. Love never "runs out". There is not a limited supply which we serve out to our selected receivers daily. You have correctly stated that you are a reflection of the world. The world fails to show love, and thus you fail to show it also. You give what you receive. So just decide what you want to receive (dedication, love understanding or whatever) and give it to someone else. It will come back to you. Try it.

The alternative is to remain in victim / I am helpless mode. There are so many people who need help. Choose one and help them, even if it is only in a very small way - to get you started on this. This can lead to great places for you. You have great potential. Or of course you can give up, or end your life, but then you will be presented with EXACTLY THE SAME PROBLEM TO SOLVE, the next time around. There is no way, long-term, that learning to love can be avoided.
