Personal Training...can I continue it??

I am trying to set my priorities for training. I have 2 sessions left, so I am essentially done next Thursday. The cost of having a personal trainer is not cheap. It can be pretty costly. I know that every penny that I have spent so far is so worth it. Having a trainer (my trainers name is Ryan) has helped me to get to a weight loss of 60 lbs in 4 months. I know without Ryan and his accountability I would not have gotten this far in 4 months. Sure I probably would have lost some weight on my own, but not nearly what I have done so far. I still have a substantial amount of weight to loss, so I feel I still need a trainer to continue on this path. I have to sacrifice a lot to pay for training each month; I have paid about $2000 so far to have a trainer. I can do 10 more sessions at a cost of about $650 plus tax, this will last 5 weeks. I am in a quagmire over what I should do. I have sat in wrote down the pro’s and con’s. The pros far outweigh the cons. The only con there is is the money. Why does everything always have to come down to money?? I have friends and family telling me that I should be able to do it on my own. I have had a trainer for 40 sessions (I got 10 of those sessions free), I know what to do, but can I do it on my own. Part of having a personal trainer is being held accountable to everything. He weighs me each time and will ask me what I have done that week; whether I lose or gain weight. He guides me through the ruff points, the slow downs of weight lose, the walls that I hit and praises me when I lose. I have agreed to certain things he has asked me to do, and to the most part I have stuck to those things. Sure I have a drink every once in a while and I have skipped a work out here and there; but for the most part I do what he says. If I do it on my own I would be accountable to myself; do I have the strength to do it on my own? Should I try it on my own for a few weeks and see how it goes? Should I take Trev’s car money and use it towards training? Should I sacrifice other things that I think I need? I want to continue having Ryan train me, but I am just not sure I can spend more money on it. I need to make a tough choice, maybe it won’t be such a tough decision and I will do the right thing for me and it won’t really be a sacrifice. The only sacrifice I would be making is against my own health, I need to do this for myself and just do it. Decisions Decisions Decisions!!!
