Hi! I'm new here!

Hello!!
My name is Lily, I'm almost 24 years old and I currently weight 160 pounds. I gained 20 pounds in April and May this year and have managed to not go over the 20 pound mark.
I used to be in the range 138-140 pounds since I was 18. How did I gain this weight you might ask? Well mostly due to switching birth control - I know you might think this isn't true but it contributed a ton. I also have recently graduated college with high grades and have been very sad about not getting into grad schools or finding a job that pays. I recently married my husband and have been waiting for my residency for the last few months, which leaves me no other option than to stay at home in bed all day. I went from being very active last Fall, going to classes, internships, etc. to finding myself a year later staying in bed all day for months only eating once if most twice a day. I can tell my weight accumulated in my thighs and legs, which is obvious because I'm pear shaped, and most of my pants don't fit anymore even though I have just a tiny bit more tummy but no more changes anywhere else. I always had big self conscious problems with my weight, especially my legs but it's never been this bad. I really don't know where to start with this, but I crave getting back at my normal weight and feeling a little bit better about myself. My family keeps bugging me about my weight because they have never seen me so fat in my life, it really frustrates me and makes me even sadder to hear that. Thankfully my husband loves the extra weight. Does anyone have any advice for me? Anyone who would like to support me through this battle is more than appreciated!
