In my pastoral experience of almost 20 years, I have helped (tried, come on!) many, and I am happy to see good results. I have no ready recipes, but here's what I recommend, in brief:
Open your heart to someone you trust (pastor, priest, psychologist etc). Take therapies. Try to be active, seeing people, talking to people, exercising your right to come and go. Do not isolate yourself, ever. Concomitantly, read the Bible, which has a message from God to your heart.
If the alternative above does not work out the desired effect, it's time you go to a psychiatrist who can prescribe correct drugs. Do not be afraid! The professional will know how to dose it so you do not become dependent for the rest of your life. Do not be prejudiced against the psychiatrist! There are cases where only, repeat, only the chemical can solve, and it comes from God, who gave intelligence and gifts to men.
Remember, life is short and beautiful. God wants the best for you!
