Hello Mam I am a susceptible man of 21. And I tend to worry a lot over miniscule mistakes and I am very much confused and afraid about my future at this point I neither know what my core problem is I allow people to hurt ,use, and even dominate me Everytime I meet with failures my confidence and my life hits Rock bottom. Most of the times I feel lonely and useless. And most of all I am shy and very much afraid to mingle with people Which is the core reason to me being lonely Please tell me how can I control myself and be strong and positive.
