Boyfriend and I have Anxiety

[bigchompers]

Hello, I'm new to this community. Nice to meet you all, you can call me Chomp/ or Chompers. Anyways, this isn't the reason why I posted this.

I'm 16 and have been dating my 18 y/o boyfriend for the past 9 months. We are a happy couple. We are always supportive and caring towards each other through everything. However, for the past month or so we've been having issues. My anxiety has gone out of control, making me question my love for him, if we were meant to be, if I'm even attracted to him, ect.,ect. Currently I am trying to get therapeutic help, and I'm not on any medication. I know definitely I want to be with him, thinking about not being together makes me sad even repulsed sometimes because I couldn't imagine being without him. Though, he also has anxiety. This is also his first relationship. In turn, this causes us to both freak out during random times. I could be anxious one minute, he asks what's wrong, I tell and then he takes it the wrong way so we both end up anxious and vice versa. One of the biggest problems is him saying I need to find a better boyfriend and related stuff when I've proved and told him countless times I will never leave his side. I tell him it's okay, but refutes with 'it's not okay' and negative things. His feelings seem to fluctuate often, he'll be happy then sad, mad, and then back to normal. We've been in this cycle forever it seems like and it drives me up the wall. I've tried to discuss multiple things about this with him but it never seems like we can improve. I know he tries hard, but I feel like I'm stuck and this will never end. I feel like I haven't done enough to help all of this go away. I don't want to break it off, I know this can all improve but we just need the extra help and boost. I need to know what I need to do to help him with his anxiety as well as tips and tricks to help get anxiety off (or at least controlled) of our minds. Thanks <3
