Need friends who have 10-15 lbs to lose

Options
I am 4 feet 11 inches. 30 year old woman. Weigh around 109-111 lbs.
I want to lose around 10-15 lbs and gain around 10 lbs is muscle in the span of one to one and a half years.
It would be really helpful to get support and motivation from people around in the same-ish journey.
