Thats fair enough, sorry but i didnt welcome you to the forum before..welcome
Im sorry you have had problems in the past and i respect your decision not to discuss them, if you have such valid reasons for needing to relactate then you can try the GP for the relactation drugs, try to get a female GP as she may be abit more understandable.
If you cant get the drugs then you can try the herbal remedies, a good one is

I will mention now that i really have no idea about relactating after a year, i know it can be done but i really dont know if it can be done without prescribed drugs from the doctor but here is the general jist of relactation, i have had to relactate because breastfeeding was getting very hard and i stopped for about 8 days and my milk supply dropped right down.
Firstly I hired a double breast pump from medela its the one i used when we were readmitted into hospital and i find it very good
http://www.medela.co.uk/UK/en/breastfeeding/products/lactina.php the one i got was the lactina electric plus. Its £45 for the first 10 days and thereafter £30 per month, they give you a pack with attachment tubes, milk storage bottle, feeding cup, some general spares for the pump, and obviously the suction things (dont know what they are called, but the things you would put on your breasts) and all this you get to keep and you also get to take off and keep the rotor arm (the yellow part) so it can be used as a hand pump aswell, you only need to send back the pump (which they send a courier free of charge to deliver next day and pick up at a date of your choice)
I then put Jakob to the breast whenever he asked, if he wanted to suck for comfort id still put him to the breast because all the extra time he was on my breasts i would start producing more milk. I would express every 3 hours, for about 20-30 minutes.
I bought a sling so that i could carry Jakob close to me when i was out and about because the closeness of your child helps to produce the hormones that make your milk, so buy or even hire a sling 1 is not too big or too old to put in a sling (i mean proper natrual slings that toddlers can sit in, not the small baby ones in the shops).
Take nice warm baths and hold warm flannels on your chest as this also stimulates milk flow, there is also certain massages you can do to help you will find alot of info on

Finally drink lots of water as you really really need the fluid to make your milk, i cant stress this one enough though i should really stress it to myself more when i am too busy and forget to stop and look after my self for a minute. eat lots of oats (thanks beanie) and make sure you are eating well, all 3 meals a day, try and get as much sleep as possible (i know its hard with a child, but nap when they do etc, it really helps) i cant really speak as i dont remember the last time i had a proper sleep lol.
I hope this helps
Good luck! it will take a while but im sure it is possible
Let us know how you get on
