Could I be depressed?

I always feel like something is my fault & I cry very often when things go wrong..Most of the time I don't even do anything wrong and I end up feeling guilty because I feel like I'm blamed for everything bad that happens to me. I deal with things that bother me because I don't want any problems or conflict with anyone..please help ❤ Nobody knows the half of what I go thru & I need the support cause I literally have no friends/family on my side because they never felt this way before and this feeling won't go away. I fear that I'll never get help because nobody understands me & I just can't take it anymore. I NEED HELP 💔
