I have relationship anxiety and it’s getting harder to deal with.. any advice?

So I apologize in advance because this might get long. I’ll minimize as much as I can. My boyfriend and I have been together for a year and some change..  I’m 23 and he’s 22. We are soooo in love and he’s the king to my WORLD.. but I want to say by I want to say September I started questioning “do I love him?” Then it went to “since I’m asking this should we break up?” It was really really really hard and it’s harder now! He knows how I’ve been feeling and it’s been EXTREMELY hard on the both of us. I’ve cried I’ve stressed and almost had panic attacks from this.. we took a break in May before my birthday which was VERY hard ao we said no to that.. we then just recently just broke up bc we both thought it was “best” and it really wasn’t. The anxiety has me feeling numb to feeling and scared all of the time. I’m scared bc as soon as we got back together the anxiety started again and now I’m faced with the question “did I do the right thing” I feel weird now that I’m back in the relationship.. overwhelmingly thankful but weird and numb and I’m not sure if it’s because of the anxiety or what.  I’m going to therapy but I’m not sure if it’s really helping as much as I want it to because I go once every other week. I’m really struggling and I’d love to hear someone’s input on how they feel or if they’re going through this or have any advice to give. This sucks and I feel like it’s going to ruin the best thing that’s ever happened to me.
