Too Much

I'm worried that by talking about my anxiety and worries I am putting too much stress on the people around me - mainly my boyfriend. I am assured that I am not burdening anyone but I am still convinced that it will become too much and I'll annoy people and drive them away - or that they won't be able to handle what I am sharing and that will cause them to resent me. I had some problems in my last relationship due to this, as my ex was upset that he couldn't do more to help which led him to react negatively when I confided in him. Now I try not to talk about any of it unless prompted but sometimes it is hard to hide my exhaustion, especially from those close to me.
