PTO mayhem

First off let me say that had I known the frustration, intense work, and general lack of volunteers and participation I would of got from joining the PTO I can honest say that I probably would not of joined. I joined in the beginning because one of the last year's members had to quit due to her parents health, also because I was basically the only regular attending parent. I went in with high expectation and hope that we (the 4 members) could turn this school around and do some new exciting.. even great things for our children's school! I got nominated as Secretary but my duties have well surpassed that of just a record keeper. I came up with what I thought were great ideas. One idea was called " change a kid's life" and what we wanted the kids to do was bring in spare change. I bought piggy banks for each classroom. Each month we would count the change and it would go into a account for helping our own families within the school. My first frustration was that I would have to do this by myself.. no one in the pto helped me. My second was when I went to collect the money I noticed that the teachers tossed aside the piggy banks. Obviously they are not into helping the families within the school. I reached out to the Media dept at our school and now have it being announced on the morning news, hopefully that will help. Another idea I had was that we could get businesses within the community to help us out via gift card, certificates, or however they could.. again this was left up to me to do solo. I don't want to sound like the other PTO mom's do nothing.. that isn't true, they all have their hands into something or another. I just feel overwelmed. I don't want to not do these projects as I think once they get going they will really make a difference, and I don't mind the work as nothing worth doing is every easy! Today my frustration is we are doing a Pantry food drive, this is a huge undergoing and it looks as once again I am flying solo! How will I do all of this alone? How is it no one sees I need help? I have meantioned how it's too big of a job but it seems as if everyone is just too busy to help.. I want to quit.. I want just give up because it's so hard, but I know that if I do there is no chance for these people I am trying to help to get help through our school. I just really wish it didn't have to be so hard to help others and to get others to help out! Also I am having a hard time managing taking care of 5 kids,being a good wife, working on the pto, 2 girls in cheerleading and trying to be there for some friends in crisis. If I were one more person I swear I could get a handle on how much work there is too do. Every time I feel like I am going to get some downtime another project has to be started. How do I manage all this.. what do I give up if anything.. where are all my answers hiding?
