Why am I so depressed all the time? I have bpd and it sucks nobody understands me and I just hate feeling alone

Hey Danielle, I have bi-polar disorder. I don't know if you have that or borderline personality disorder, but as someone with depression, I know how much it absolutely sucks. Do you feel like your friends and family don't understand what you're going through? And do you feel like if you don't try and hide it all, they'll abandon you completely? I know how much it all hurts, and I know how much it eats away at your mind. But please don't ever give up. Look at you. You've gone through a long time living with such an awful illness and you're still here, no matter how many times you've wanted to give up! You really deserve credit for that. I can't promise you that things will get better immediately, but the poison will leave gradually. It's really awful that you feel alone and misunderstood by the people around you. :( Hopefully with an increasing understanding of mental health, the people around us will learn how it really is to be in our positions.

I hope you stay as strong as you are. Things won't be so stormy all the time. There are good times ahead, I promise you. <3
