TW: Body Image, Food, and Dieting

Okay so I'm insanely insecure with my body recently. I had my implant taken out because i was having insane break outs and gained a lot of weight. However since taking it out nothing has improved and I don't even know where to start. I'm considering trying keto but always worry about the more restrictive diets because I don't have a good relationship with food and experience issues stemming from a past ED. If anyone has any advice they can offer at all it would be greatly appreciated because I'm feeling extremely helpless right now. And I don't want to fall back into old habits.
