Lately I’ve been feeling alone

Me and my boyfriend have been having problems with each other. It’s my fault most the times. It’s just not the same energy anymore. He’s been going through a lot and I feel like I’m adding on to them to his problems. I feel horrible. I don’t mean to but it just happens. I’ve tried to reach out to my friends and talk but they have other things to do or just don’t wanna talk to me. I feel like I’m falling into a hole and I don’t know what to do anymore. I feel like I’m losing everything.
