I know this will sound more on the “non-problem” side of this sub but it’s been eating at me for so long and I need a bit of help…

 I (16f) and my boyfriend (17m) have been best friends since we were 13 &amp; 14 and have dating for almost a year with our anniversary coming up on the 23rd of March. We and others believe that our relationship is very healthy and loving especially considering we’re still teens. We both take baby steps when becoming more intimate with each other, we see each other as often as possible (1-3 times every month since neither of us can drive), and we talk almost every day and communicate when we can’t. Ive have GAD since I was 11 and he knows about this and understands since he’s gone through major depression at around the same age and has a sister with my mental illness. Lately I’ve been paranoid about him suddenly leaving me and never talking to me again and I’ve been using social media to take my mind off of it but I keep seeing posts with other women and girls saying “my bf dumped me out of nowhere and is refusing to even look at me.” I know for the most part that this may not be as truthful as it seems since sometimes we can ignore red flags and/or cause the relationship fall apart but the thought of him gone forever makes me go into an anxiety attack. Plus, me and him both have abusive (mentally/physically ) families and we’re basically each other’s ticket to a better life. I know he probably won’t be one of the guys to randomly leave due to himself being antisocial to most but I can’t shake the feeling that he just will and now that I’m having family issues again he’s one of the only things keeping me going. Could someone please give me some closure or things to look out for just to give me peace of mind?
