Notanan2, you can't make friends until you have made their acquaintance! I don't think that you can force a friendship, but keep meeting people, and making the effort to stay in touch will allow friendships to develop.
There is a lot of evidence that the larger your network of friends/acquaintances the better your health and wellbeing.
I was in a similar position working so that I couldn't get out (DH is VERY unkeen for me to go out at night). We'd moved constantly since we were married and so I'd lost touch with most people I knew.
I joined U3a, which has a lot of groups everything from bridge, to latin, vegetable gardening, knitting, singing, walking, you name it.
I also went on facebook and finally found school friends I'd lost for years. One drove up to see me yesterday.
I joined a group of ladies who 'meet for lunch' one day a month. I found them through the local website.
I haven't found a best friend yet, but at least I can natter now!
