Why do i feel depressed and angry all the sudden occasionaly for no reason ?

Probably because you are holding on to something within you mind like; past mistake, failure, missed opportunity and so on. You don't know how to let go of the past and it keeps coming to your mind thus, it keeps making you angry for no reason. And secondly, it'll be because you are so desperate to succeed on something but, it ain't going the way you like. It could also be lack of sufficient funds, work, or due to stress. These are few issues that could get you angry for no reasons. You should reflect and try to be at peace with yourself.

This could be for many reasons. Have your diet or sleep habits changed? Are you getting too much coffee/sugar not enough water? Are you getting enough physical exercise/sunshine? Have quiet moments for meditation or hobbying been elimated from your schedule? After checking for for all of the above then check your surroundings for any increases in stress levels or demands, new co worker? relationship troubles? Try journaling to pin point what is triggering your mood to change.

It could be because of many reasons, allow me to state some and maybe you can find the most convenient point to your status: 1) You may have remembered a bad situation, memory, person or event occurred in the past. This usually causes sadness easily as you remember something that triggers depression easily. 2) You may have experienced something that has annoyed you in your day. It could be the simplest thing like spilling coffee, living in a noisy or polluted environment, or even hearing or getting involved in a fight. 3) You could've experience a very simple unfortunate event like losing a game or similar stuff. All these imply that you're easily affected by the simplest events, which you should watch out so you don't get mood swings easily.

To feel like that, it seems that there might be quite a bit bothering you or there is a lot going on in your life leaving you feeling overwhelmed. When I was feeling like that it eventually started to be more than ocassionaliy I felt that way. Eventually my friends noticed that I didn't seem myself and once I opened up to them, they really wanted me to find a licensed professional to talk to. I honestly wish I had decided to find someone sooner, because while I am not okay all the time, I don't feel as depressed as often and even when I do I feel better prepared to handle the emotion.

When you have intense feelings that seem to be more powerful than the situation logically warrants, it's an indication that you have powerful unresolved emotions from the past. Ask yourself, at what other times in my life did have I felt feelings similar to this? If this question reminds you of painful memories then you may want to consider seeking some kind of additional resolution for those feelings. The best way to resolve these would be to bring them up with a counselor. If that isn't viable then a listener or a trusted friend would suffice. Another option is to take some time completely alone to simply pay attention to those powerful feelings. Yet another option is to write down the memories that awaken these intense feelings. You can simply describe what happened and how it made you feel. Any of these activities can help to process that unresolved emotion that's lingering within. The more powerful the feelings, the more resolution they need.
