So I'm 20 years old been told I have anxiety and IBS. For the past year now I have had a very uncomfortable feeling in my chest, get light headed quite a lot and my vision sometimes goes funny, I suffer from constipation and have bad pains in my stomach at times, there's sometimes blood when I wipe after doing the toilet and everytime I go to a doctor they tell me it's just my anxiety or IBS playing up but I'm worried incase it's something worse. If anybody has experienced this or is experiencing it can you give me any tips on what I can do to make it stop
