Been not well for a month going out of my mind

It started a month ago with a gum infection thought I was having a reaction to the antibiotics so stopped taking them and got amoxicillin then given more antibiotics for my chest from doctor for my chest he said I had a viral too still not well and found I had a kidney infection so more antibiotics finished those last Monday evening went back to doctor and got bloods taken all came back normal have to leave a stool sample in.. doctor gave me carbocistine for my sinus and anti sick meds... I still feel ill and still have diarreha along with shakes I am now getting tightness in my chest I just wish I was better I am going out of my mind please someone talk to me

After all those antibiotics it make sense. And then it's feeding your anxiety, just get on a healthy food plan have some probiotics or drink a kumbacha for a few days and get you system back on track. You are on your way to being healed just give yourself recovery time and remember your anxiety symptoms are just that anxiety. 

I really can't settle myself this evening.. my chest is tight and heart racing when I try and relax I just get worse.. I try my deep breathing but it's not working

Times like that I try to take a shower or bath a good long hot one even if I already took one I do it again then  go set and do my deep breathing have some herb tea and if I just can't settle I go ahead and take a sleeping pill. That puts me out if all else fails.
