Hi,
Time is the solution for many such problems, you have to come out of your
depression by overcoming it by intended decision to have a new fresh lease of life. Or you can get an assistance of a
Psychiatrist if the problem is not improved within a few weeks.
This is just a small problem if you really look at it. As your Father is already finding a girl for a marriage, you have to prepare for a new life. Once you decide I am sure you will come out of this small problem very fast and swiftly and will have a normal sexual functions.
First of all, you have to become very social, mix up with people, friends and family, get involved into a constructive activity, hobby or so in such a way that you are busy all the time. This will not give you time to get engaged into
masturbation. GO for outings / vacation / tours. Try not to be alone at all. This will automatically suppress your feelings and alter them to more positive approach and help concentration.
Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Iven Romic Rommstein, General Surgeon
