You don't have to apologize for anything. I, myself, suffer from something they labeled as irritable depression (I get angry before I get really depressed), and in moments where I'm lost and just so close to giving up, I really don't pay any mind to anything people say to me because in the moment, I just don't give a crap. It isn't until later that it actually resonates me, and those are the times where it has more of an impact. Even when people don't thank me or don't accept it at the time, I will always be there to say something... ANYTHING to help whether it will resonate right then and there or later on.
Either way, you are most certainly welcome. I do my best to provide some type of hope/love/happiness/comfort in people's dark times. Continue staying strong, you're doing so much better. <3
