I'm 19 years old, female. In October 2017 I was diagnosed as being deficient in B12. I initially went to the doctors for headaches and he ran a complete blood test. My B12 count was 92. I've previously suffered from iron deficiency anaemia with my lowest count being 4. I'm also deficient in Vitamin D and folic acid. I suffer from extreme fatigue, irritability, sensations in my mid-back as if somebody is actually pressing there (I've seen three different doctors who just said it's nothing sinister but didn't try to find out what caused it!). I suffered with anxiety and depression when I was 12 to around 15. Doctor's put it down to bullying but after researching it is likely this was due to my low levels of B12 as it takes years to reach the level of my deficiency. I'm currently taking Fultium D3 800iu twice daily, ferrous fumarate twice a day, cetirizine for allergies, and the doctor repeatedly told me my symptoms such as fatigue, crying (because I have NO energy), and irritability were down to depression! I told her I was not depressed and burst out crying in front of her because I felt I was not being listened to! A second visit resulted in her referring me to a specialist for my fatigue (when asked which department she said she doesn't know and will have to research into it!) and me having to "prove her wrong" by taking a months worth of Citalopram 10mg to see if that eases my fatigue which it has not. She said if the Citalopram does not work she will give me another round of loading doses! I had 6 or 7 loading doses in October/November of 2017. These didn't seem to help and I remember asking every time I had an injection when I would start feeling better. They must have worked slowly because in January I started feeling extremely tired again, sleeping for up to 16 hours a day, had to stop going to college which affects my grades and attendance, had the funny sensations in my back again, mood swings and general body weakness. Went to see the doctor who dismissed my request for a blood test to see if the B12 was as low as last time. He said B12 is not routinely tested which I understand but I just wanted to see if the B12 had gone down really low again as you can't expect a one size fits all with medication. He was really rude and put me on propranolol because the amitriptyline for headaches was giving me side effects. In February, went back to the doctor and begged for my B12 early she said no it's to stay to three monthly cycles. She took me off propranolol and said that would make me more fatigued!! I feel like they keep putting me on and taking me off medication without thinking about the effects it is having on my body! Managed to convince her to give me it at 10 weeks. I felt great for one to two weeks after my injection and then all the symptoms returned! The brain fog is awful, I forgot my pin at a cash point, i can't spell basic words at times, I'm sleeping up to 16 hours a day again even if I'm not going out the house or exerting myself and I'm getting headaches and fatigue again. This means my injection is not due until May (back to three monthly). I'm desperate to have the injection, and I'm now seriously considering self-injecting! How do I go about this? Is it worth self-injecting at my age? My symptoms aren't as severe as other people, but I'm 19, unable to absorb B12, have exams that will influence whether I get into university in September or not and I can't keep staying in bed for what feels like days at a time!
My questions are;
Where should I buy the B12 ampoules?
What size needles should I get? (one for drawing up the B12 and another for injection)
Where can I buy needles and sharps bins?
How often shall I self inject? (my mum is a nurse so she can inject for me until I feel comfortable!)
Has anybody else had good results from self injecting??
I apologise this is such a long post, I'm just at my wits end and tired of being passed around different doctors who don't treat me like a person, just a number!
