What can i use if i feel angry the whole day and sometimes depressed aswell and the weight is very up and down?

Several options: 1. CBT skills training (with a professional or self-help tool/book) can help you learn to (a) recognize these factors as they happen, and (b) identify and choose alternate responses to reduce depression/anger. 2. You may consider medication management for depression. 3. engage in meaningul activities/exercise - being active and engaged (vs. passive/stewing) can lessen depression/anger. Be well.
