How long after breakup did you start dating ?

I left my narcissistic ex after being together for 4 years. I am feeling lonely, but I know it’s all apart of the process. I do not plan on rushing into another relationship. I want to take time out to work on myself; losing weight, being 10000% financially independent, falling in love with myself, working on childhood trauma etc, but I don’t know how long I should wait before even looking to date again.

I also have 2 kids.

I grew up being an emotionally independent child as I grew up with narcissistic parents and I leaned on my partner for emotional support. He was there for me throughout everything and now I don’t have anyone to lean on, but I’m expected to be strong for myself and the two kids I’m raising. I don’t have close friends or family members to lean on and I’m simply scared of trusting people and opening up to them. I also think that I have too many problems to burden one individual with and I can’t afford counseling atm.
