Feel low, happens a lot. To get over it.

There are fee days when I am upset, fue to the happenings around me, due to the conditions i might be going through and due to the low confidence I observe most of the times for major of the tasks; but then there are 5hose times when I completely go out of the situation/surrounding/whatever I might be doing, and start feeling low. Happened so many times that I just wanted to cry, and did, but the feeling didn't go away. After few friends assuring that whatever happens, they will help me look after it, I somewhat felt better. But the cycle continues. And happens at any point. Not needed that happens regularly. The feeling was always there and it used to happen to me since past 2 to 3 years but now the frequency is increased and I have started crying out of no reason and for a longer time. Sometimes I think this is depression but can not come up with any conclusion and seeking for help to get over it.
