I've suffered from anxiety all my life although only in the last few years i've really identified the symptoms as that,ie pins and needles all over and feeling het up tense when stressed or put under pressure,but recently over the last 6 weeks after the xmas holiday which was very stressfull my anxiety has rocketed to tight chest heart pounding and the main problem is sleep ,i've never in my life had problems sleeping but now i am lucky to get 3 or 4 hours as i awake sweating and stomach burning and feeling dread ect. What doesn't help is my ocd thinking worst case senarios and this anxiety just keeps on coming plus this is all leading to me feeling depressed ,been to the doctors and he prescribed 10mg citalopram which i've been on for 2 weeks but not sure if that is causing more anxiety or not .I am a regular runner and this has helped keep my anxiety to liveable amounts but nothing seems to stop this severe anxiety ,I feel like i'm going nuts i keep questioning myself and beating myself up over everything and can't stop thinking bad thoughts about things and i'm worried that i'm going to have to go off sick if this continues ,but my job is such a part of my routine that the thought is stressing me more. Has anyone been through and come out of this severe type of anxiety? ,any tips ,thanks
