ignorance is bliss

I have been dealing with mental issues for almost a decade now, i'm 20 now. primarily I have been dealing with clinical depression, while I feel that I mask most of my feelings of course this can not be a 24/7 mask and slips can happen. 

I feel that my family are really "blind," so to say when it comes to be showing outwardly depression symptoms. While I have never confided to anyone irl about my mental issues except for perhaps once. But i think my family are afraid to say that I am depressed or that I may have depression. This has caused my life to be really hard. I feel that I have been living two distinct lives since forever. 

A lot of the time I find it hard to get out of bed especially on the weekends. My mental health on top of school make me stressed out most of the time so on the weekends all I want to do is stay inside and sleep. While my mom has acknowledged that my behavior is not normal, she simply says because I am anti-social (which is a lie). I have no problem talking to people, having conversations and living a sociable life. 

I just hate having to keep up with this lie of a life but at this point it feels better to keep my mouth shut and suffer rather than have my life turn upside down if i spoke the truth. I want help I just can't bear the consequences.
