Extra support from bf through anxiety

Would I be bothering my SO too much with some small anxieties I have?

Ok hi. So I kinda been struggling with anxiety a little. I been overcoming it on my own because one, it’s annoying to me and others and two, I can’t afford a therapist. However it’s still bits and pieces. Yesterday my bf and I got into a little tiff. Nothing bad but I had to explain to him again that it makes it more difficult for me when he gets irritated too fast when I’m trying to explain what’s going on through my mind. I mean I think it’s gotten ALOT better but it’s from when I was a kid and I had to adapt blah blah. This isn’t about that bc he understands and he himself is trying to work with me as I work through it which I adore him for.

So now we’ve been together for about 2 years and there are nights (he doesn’t know) where I’m up and can’t sleep because I’m just overwhelmed and not scared but just not ok. I just want to call someone , well him. Just to talk to help me in a way calm down. But I always feel like that’s just too childish almost. Especially now that he went into the military and he is currently in schooling. So he has a roommate and all. We just started doing LDR so that’s made it harder for me to be able to relax sometimes but not impossible. Throughout the day I’m mostly fine. Like any other human, still got responsibilities lol. But it’s the night where it hits.

Let me be clear, I do not and would not use him as an emotional crutch. I’ve been one of those before and it’s draining, I wouldn’t even want or think to put him in that type of position. However should and/or would it be ok if I just asked for that extra support through this ? He knows I’m weird and like I was mentioning previously , there is still things I’m tryna work through that tends to get him irritated and it makes it worse so I had to ask him on that as well to work with me. Would it just be too much? I just think it’s too much for me to go through alone sometimes..
