To @OP;
Depression (which usually contains sadness, emptiness, etc.) is a mental health disorder & depending on its level can cause anything between tiredness, lack of ambition, up to heavy suicidal thoughts. I've experienced the whole spectrum, & back in days, I've committed to an unsuccessful suicide. At the end of the day, I'm still alive and typing this stuff.
Due to having an introvert personality type, I tried to handle it on my own, which wasn't successful up until the time I found a value to life (I lost it again in recent years, but I'm not in that mood no more) after that unsuccessful suicide.
So based on the level of depression that you're experiencing, you should consider
taking therapy sessions and
trying to do things that make you enjoy yourself. For me, I found coding & music production so enjoyable that I can't get enough of it.
I hope you overcome the current situation cause life can always[?] have some better days for you.
