Breastfeeding

I had to stop breastfeeding at about 1 and a half months after I had my son due to stress and lack of pumping. I have been told many times that I can start my milk production again. I have also been told that there is no point now that my son is almost 6 months old and has been on formula for so long. I am a teen mom and I am still in school. School it almost over so I was thinking about trying this summer. What do you guys think? Should I even bother or should I just move on and wait until I have more children and breastfeed them. I do really miss the connection I had when breastfeeding my son and I loved the fact that I could provide him with what he needed.
