Nothing personal, but I'm betting every single person here has gone through pain and misery due to enjoying the colors of life. My uncle lives in black and white and he's one of the unhappiest people I've ever met.
Life is pain, life is sorrow, life is color, life is love, life is beauty.
I shot meth into my arm using needles, smoked black tar opium while in a very abusive relationship with someone 9 years older than me at the age of 20. I was thrown out onto the streets as a strung out junkie and I had blood poisoning. I went straight to the hospital with only the clothes on my back and had to go back to my parents place. I spent 2 weeks rehabbing at my parents before I was healthy enough to go back to work, with the majority of my so-called "friends" (the people I got high with) turning their back on me and stealing my stuff. I had to start completely over.
My "solution" to my best friend having a nervous breakdown and divorcing my other best friend back in 2009 was to dive into a bottle for 2 years. It was only due to my husband nearly dying of a mysterious illness for over 6 months in 2011 that we still can't figure out that got me to quit drinking. Daily rounds of blood tests, different specialists, and he had 100 pounds of water weight. He was going into cardiac failure (not a heart attack, but that happens before a HA does,) and had to be put on an oxygen machine (not a tank, a fully fledged machine) because his blood oxygen was dangerously low.
For those that know medicine, he was averaging between 75-80 oxygen level in his blood. A healthy person is at 95+. I thought I was going to be a widow at the age of 32. We don't know why or how, but once we started to remove the water weight via pills, the rest of the symptoms left. Our doctor even told us that she still doesn't know, none of the specialists know and it could happen again at any time. His stamina hasn't been the same since he was sick.
After all of that, you know what? I wouldn't change a thing, the huge mistakes and all. I have some very close friends that have stuck by me through thick and thin, one of which for nearly 20 years now. He was there when I was screwed up. He stayed my best friend even after I almost kicked out the windshield of his car because (ironically) he was telling me I was doing too many drugs. He's gotten through his divorce and is marrying a wonderful woman now. He's happy and I get to be there for it.
With my husband, he's very dear to me. It isn't just our marriage, it's our friendship and our sense of humor. Thanks to us sticking through it, we got to go up to the Continental Divide for the first time, we got to see all of our nieces and nephews being born. We both have a good relationship with our family and we're happy together. It took work, but we're here. He cheers me on while I'm playing DA:I while I cheer him when he plays Kirball Space Program. We don't have "a" conversation, we have The Conversation that just stops and starts. 
The point is that I know about pain. I'm not claiming to have a cornered market on the subject, but I've been there. I can promise that no matter how much it can hurt, it's truly worth seeing the world in all of it's color. The love and the friendship and the hope balances itself out. I think about the person I was when I was about to slash my wrists while tweaked out of my gourd. I think about the person I was when drinking a huge bottle of 100 proof schnapps (Rumplemintz, specifically) a day. I think about my husband nearly dying and yes, all of that came with a lot of pain and heartache.
Then I stop and think about everything that came after it. All the years of laughter and music and experiences that I would never have allowed myself if I had just shut down and starting seeing the world in black and white. Hana, I know you're hurting, but I promise it will get better. <hugs>
Edit: I didn't see your last post until after I posted this. You don't have to give any sort of an answer, I just wanted to throw this out there.
