I have been so used to having the goal of heaven and pleasing God as my purpose in life to the point where, without my old religion, I feel empty, and almost without meaning. It is because of this that I wonder if Buddhism has something similar to offer...

thank you Seeker

if your mind gains enlightenment, it will feel completely satisfied & fulfilled, because all negative emotions (such as discontent, feeling meaningless, etc) will be dissolved. the mind will be pure radiance, peace, understanding & light. an "inner purpose" will be fulfilled

as for an "outer purpose", buddhism also recommends helping others with suffering (because the world is full of human suffering). please consider the fulfilment & happiness you feel, when you genuinely help another in need

many Christian people devote their lives to helping others, which is similar to the Buddhist focus of cultivating compassion

kind regards

As for different goals besides personal enlightenment Mahayana Buddhism teaches that you should strive to "liberate all sentient beings." Meaning you should help others reach enlightenment.
