I'm going to disagree with the above here, since you're quite young and inexperienced. Love hurts. Drugs don't change this, they just suppress it. You don't say if you had an anxiety problem before this happened, but you do say the sleep problem happened only after this breakup occurred. Welcome to the world. It will pass. Frequent urination is common when you're anxious, and if you see a regular doctor about this or especially a urologist, be careful because all they know how to do is put you on other medication when if this problem only has arisen since the breakup it, too, is probably just a temporary emotional response to a stressful event. The best thing, assuming these are in fact new only since the breakup, is to see a counselor or psychologist and talk it out, not to seek out something that suppresses it. You're not sick, at least by what you're saying, you're sad. And the sex isn't really important here, the loss is. Give this time, get the suffering over with and learn to move on -- it will be a valuable lesson.
Taking anti -anxiety drug without consultation with a doctor may prove dangerous.Type of the drug,its side effect, dosage are important factors which are known to medical professionals.
Breaking up relationship has a traumatic effect . The trauma's effect will be reduced with time.For frequent urination, you need advice of urologist. You will be normal if you consult a doctor. You may not tell your parent about sex, You can tell your doctor about sex and symptoms. Doctors usually do not give details to other persons, even to your parents. You may request the doctor not to tell about sex to your parents. Once you pass this stage you will have a anxiety-free life. Self treatment is undesirable in your case...........Be brave and face the problem.
Maybe you should see your Dr and tell them the medication is'nt working. It sounds like you have depression going on on top of your anxiety. Are you in any kind of therapy? Is this your family Dr that prescribed the anxiety medication?
