Dear Welcome to HCM We understand your concerns I went through your description. I suggest you not to worry much. Masturbation is not harmful if done moderately. One masturbation daily up to an age of 18 is normal. After that it might become thrice or four times a week. Very normal. Young people loses the interest in masturbation when new interests like studies and career comes up. You do not have to worry about masturbation. But you should worry about your anxiety associated with it. That is why you are unable to sleep. Also from this it is clear that you have no interest in your studies and career. Therefore please change priorities and you shall be alright. You might need psychological counseling., I am more than happy to provide telephone psychological counseling through healthcaremagic. Contact me through customer care, www.healthcaremagic.com. Hope this answers your query. Available for further clarifications. Good luck.
