There are community mental health centers as well as some psychological services that work either for free or on a sliding scale (they will charge based on income/need) and I recommend you try to figure out if there is one of those in your local area. If you feel as if you have an eating disorder the best thing you can do is get help. A lot of places will do pro bono work for those who cannot afford treatment, but it is best to try to receive some treatment and a diagnosis before you eating patterns worsen. I hope this helps!
