Welcome to Psych Central (PC) navya_mishna. Sorry to hear you have been suffering from your emotions and dreams. There seem to be conflicting emotions. When awake you are angry and feeling abandoned. When you sleep you feel like you cannot work things out with your ex. Trying to get back someone who dumped you can be most frustrating. Closure for some is moving on to other relationships that don't give you nightmares.

Some people at PC will find a therapist will also help them sort out the roots of their life.

Getting enough sleep may be the single one thing that keeps people in balance. If you are not sleeping or having bad side affects, contact your psychiatrist and tell him what is happening so you can make adjustments.

I find that mindfulness (meditation without the religion) and breath awareness help me cope with stress.

Many people find compassionate, caring people here at PC. Some people find the forums give them the compassion and empathy they seek. http://forums.psychcentral.com
