How can i feel better inside? i feel so angry & frustrated lately, & i can't handle it because i'm taking most of it out on my mom. what's wrong w/me?

The process you: Mention is called "displacement." the cause of our anger/frustration is placed upon the handiest person, in this case your mom. You need to figure out the sources of your anger and frustration and make plans for step by step changes. A mental health professional can help you. Congrats on seeing that you are displacing and that you asked a question. A good first step.

Depression: Is a mood disorder and a serious medical condition. There are many different types of depression disorders. At the same time there are many effective treatments and self-help strategies. If clinical depression is suspected, you should be referred to a psychiatrist for management. Rec.: see your pcp for evaluation and referral.

See a Therapist: It would be helpful to have someone to talk to and help you work out what is going on. Have you ever met with a psychologist? Cognitive behavioral therapy can be very helpful. Also, remember that what you feel is based on how you interpret your current situation and life. Change your interpretation and you can change how you feel.
