Kat: I know how you are feeling: I had autoimmune stuff come up in November and the medication I was put on caused me to puff up like a blow fish and it really put me in a bad place mentally. #1 listed side effect of the other med: weight gain
Having clothes not zip while staying 100% on plan started making me crazy.
I stuck it out: my body adjusted to the meds and the water retention went away. I'm now at goal and still dealing with the autoimmune stuff but it is under control. I had even considered delaying treatment until I lost all the weight: looking back - I'm glad that's not what I chose.
Just remember: this is temporary: it too shall pass. If you stay on plan the weight will go away. Its only water.
I'm sorry you are going through this and that it has caused other heath issues to act up too.
