You know, I took an abnormal psych class and by the end I felt like I had every known psychological disorder. Lol, it was terrible.
Here's my suggestion- write down every physical or mental symptom you are experiencing and rate it from 1-5, 5 being it bugs you every day and you can't deal with it, 1 being it's really not too bad and you could probably live with it if you had to.
Take this list into a doctor and see what she says. If the doctor doesn't come up with something to help you with the 3's, 4's and 5's, take it to a different doctor and then a psychiatrist/psychologist and see if she can help you.
Also, you might want to stop in to a psychologist if you feel you need help dealing with these horrible things you've had to deal with recently, when things like that go wrong sometimes you just need someone to talk to and help you through it.
One last thought- our breasts change in lumpiness throughout our menstrual cycle, so it can from time to time just feel lumpier than normal. Have you been doing monthly self exams? Start if you aren't, and you will know what they normally feel like so you have something better to compare it to. Do them at the same time in your cycle each time.
Hope you find some answers-
