do you know the difference between PTSD, Bipolar, and Clinically depressed. it can be confusing but only a therapist can tell you what your having.
i was dignosised with major depression and i used to take prozac, some people who are bipolar take prozac.
i cried for no reason, when i took the medication it was a difference in my mood.
so i agree with you when you say you need to talk to a therapist, and possibly get on medication especially because of what you went through as a child.
i suffered from 18 years of depression, i really feel like my birth control pills is balancing my mood. if you dont have insurance you can try mood enhancers like SamE, HPT-5, St.Johns Worth, Calcium pills...are all mood enhancers.
i was also told to cleanse your colon.
you may think it is crazy but it is worth a try.
