<human>: Can you succinctly summarize the text in 1-3 sentences?

I've become really attached and clingy to my best friend and crush, Jessica. 

Backstory: I've known Jessica for 5 years and she's always been a good friend and has always been there for me. About 2 years ago I fell into a deep spiraling depression, got really bad into drugs and alcohol to try to escape it. I became really addicted, but eventually became sober again with the help of my girlfriend and Jessica (07/07/14 is my date, almost a year sober, woot!)

After that my girlfriend dumped me and I was left with just Jessica. It put me in a pretty bad place and I almost relapsed, but Jessica helped me and we became really close after that. Other than maybe one other person, Jessica was all that I had. Jessica and I dropped out of school and spent all of this year. I would see her every single day and stay over at her house weeks at a time. 

I really started to depend on her and I started to fall for her, bad. I just wanted to talk to her and be with her all the time, she felt like home to me. When I wasn't with her I just slept and sulked around all day. Jessica became my everything. She's always on my mind, I feel obsessive and I hate it. A situation came up to where I can't see her as much anymore and it's slowly destroying me. Now I'm just blowing up her phone all time, and do my best I can do to see her. I don't know what to do, I wanna stop being so attached, but not talking to her just freaks me out, I get scared she's just gonna stop talking to me or abandon me or something. Honestly I feel like she's the only thing keeping me alive and that scares me. I'm losing my mind but I don't know what else to do.
<bot>: I'm terribly attached to my best friend and crush, Jessica. I can barely go an hour without messaging her. I get scared she's gonna just stop talking to me one day. Don't know what to do.
