Depression. To fulfill it anymore.

I have been in a state of anxiety since 7 years of my life as much as I can recall. I am going through vulnerability and it has become very hard to breathe in my skin. I know my problems seems normal like any other human but I am having very hard time in dealing with them. I fail to express my problems though I have tried too hard to discuss with people around but they couldn't. And I choose to lie about each situation and now it has gotten very hard for me to distinguish between truth and lie. I am in a state of denial most of the time and very high expectations in the situations. I have started loosing track of things as my brain seems inefficiently working recently. I am always in a fear loosing and tends to hold on to things too much that it automatically gets spoiled. I am not sure my state of mind needs medical help or not but am really concerned about my state. I understand my responsibilities towards many people but it's seems impossible to fulfill it anymore.
