Woke up went to Drs for fasting blood test and felt ok . About 11am felt really sick about 12.30 had a piece of bread for lunch and still felt yuck. Kept drinking water . Then about 1pm started to feel strange really strange . Went outside to walk around and did this for about 20 mins . Sat outside and the heart rate went up , felt like I wanted to vomit , pass out , I just didn't know what to do with myself I couldn't sit and walking was really hard . I tried my hardest to get through this fkn panic attack . I ended up taking a Kalma but took a good 40 mins to kick in . I went to bed and slept . But ever since I have got up I'm so so exhausted , just drained . Why ?
