Thank you for all of the wonderful suggestions everyone.
@thinkingchickens: The nearest
petsmart will probably take me about 4 hours to ride my bike to. I would sure lose a lot of weight, but in this heat I think I'd get heatstroke my first day
The nearest pet store is small so I'd probably have to cashier as well as petcare, but if retail becomes my only option, they will be the first place I try. Right now I can't justify volunteering anywhere to my boyfriend, but when I have a job with reliable days off, I am either going to volunteer at the zoo here or the local wildlife sanctuary. I miss the aquarium with all of my heart, so hopefully I'll meet similar animals and people at either of those places.
@Gullie and Katie: I do have an ad up on craigslist and one regular client for petsitting (for both in my home and those that I can get to in a reasonable time on my bike). There are just not enough people here that need their pets watched I guess.
@melodie: I asked my boyfriend that because his brother's girlfriend does online classes at the same school, but he says they don't do biology online. I will look into it myself though to be sure. If they do you can bet I'll enroll!!! Thank you for the encouragement. I did give up before, but after volunteering at the aquarium and seeing/doing all of the things I did, I will never give up on myself again.
