You are on an insufficient dose to have a TSH of 4.2 so I hope the Endo is sympathetic. All of the following are far too low and will cause symptoms. Your present dose is too small.
Others more knowledgeable than me will respond with advice:
Your vitamin levels are far too low, probably as direct result of being under medicated.
Your GP should have been increasing your dose of Levothyroxine
Levothroxine should be increased in 25mcg steps, retested 6-8 weeks after each increase. Dose increased until TSH is around or just under one and FT4 towards top of range and FT3 at least half way in range
Official NHS guidelines saying TSH should be between 0.2 and 2.0 when on Levothyroxine
(Many of us need TSH nearer 0.2 than 2.0 to feel well)
Dr Toft, past president of the British Thyroid Association and leading endocrinologist, states in Pulse Magazine,
"The appropriate dose of levothyroxine is that which restores euthyroidism and serum TSH to the lower part of the reference range - 0.2-0.5mU/l.
In this case, free thyroxine is likely to be in the upper part of its reference range or even slightly elevated – 18-22pmol/l.
Most patients will feel well in that circumstance. But some need a higher dose of levothyroxine to suppress serum TSH and then the serum-free T4 concentration will be elevated at around 24-28pmol/l.
This 'exogenous subclinical hyperthyroidism' is not dangerous as long as serum T3 is unequivocally normal – that is, serum total around T3 1.7nmol/l (reference range 1.0-2.2nmol/l)."

Professor Toft recent article saying, T3 may be necessary for many. Note especially his comments on current inadequate treatment following thyroidectomy
If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 3-5 days before any blood tests, as biotin can falsely affect test results
Ferritin is also too low. Eating liver or liver pate once a week should help improve. Needs to be a minimum of 70
Always take Levo on empty stomach and then nothing apart from water for at least an hour after. Many take on waking, but it may be more convenient and possibly more effective taken at bedtime
Many people find Levothyroxine brands are not interchangeable. Once you find a brand that suits you, best to make sure to only get that one at each prescription. Watch out for brand change when dose is increased
Many people do not get on with Teva brand of Levothyroxine
Your vitamin D is dire. When was this test done? Have you seen GP since these results?
Suggest you get an urgent appointment with any GP early next week. Your vitamin D needs supplementing at loading dose urgently.
PTH (para Thyroid hormone) is way above range. This is because vitamin D is extremely deficient. Your calcium is also low. These indicate vitamin D has been low for some time
I really appreciate you taking the time to look at and think about my results.
My tests were last Friday. I went yesterday to get the results and the doctor gave me colecalciferol 800 IU capsules, 1 to be taken each day. (Looking at the links you sent this is not nearly enough). She said it would be a start before my endo appointment.
I said to her that I thought my B12 was too low and my TSH too high but she said it was in her ranges and the endo could make the decision on that.
To give her credit, she’s the one who decided on these tests. The last GP claimed to be a thyroid expert, wanted to lower my dose and said that the only thing wrong with me was that I’m unhappy at work (because I commented that I only sleep and work and that’s no life)
Meant to say .... I always take levo just before I go to sleep, always take the same brand (Almus - mercury pharma does nothing for me) and I’m gluten free.
Calcium will naturally increase as vitamin D improves. This is why it's recommended to also supplement vitamin K2 Mk7. This helps send the increased calcium to the bones where it should go, rather than fur up arteries.
Yes B12 is too low, if you have symptoms of low B12 then you need further testing before starting supplements
