worsening state

as you all know, I have been diagnosed with anxiety and depression. What I dont think I have mentioned to anyone on here is that a few months ago I was sent to the hospital for an intentional overdose on my antidepressants. It wasn't a suicide attempt, it was coping that went horribly wrong. But ever since then o thought things would have to get better.. I mean how could they get worse than hitting rock bottom and everyone finding out? Well.. They did. Now its not only anxiety. My depression is back and progressing at a seemingly noticable rate. I am overly irritable very very easily. My anxiety is causing me stomach pains, migraines, difficulty falling asleep, trouble staying asleep, paranoia and delusions. I am scared at the drop of that and if people are too close to me or anything of that sort I freak out and can not breathe. Just the other day, my boyfriend and I were out at a restaurant and I could have sworn he kept giving me this look like he was going to hurt me and he knew exactly how he was going to do it. I hate all this knew stuff that I am dealing with and I was just wondering of anyone had any advice or a story of their own that they would like to sharem
