How to find the determination to lose weight

With all the housework and baby. I feel lack of motivation to lose weight I actually gained weight now I want to start doing something positive.

I do everything first and put myself last I feel stressed to I wish I knew how to drive a car. I have anxiety so I decided as a teenager I didn't want to drive but being stuck at home sucks.

I'm not sure how to find and keep that determination.

I have seen women do it. I know this doctor at three months old left baby to a daycare and went back to work seeing sick patients even if she had to go home see kids she went to college against all odds poverty discrimination and I see people they work go to school have kids do daycares preschool kinder and they exercise and some even have the time to put on make up get hair nails all looking together.

How do they get out of the bed and do that everyday

How do people go above what they think is possible

Especially w kids because you get so attached feel sad to drop them off

So right now I'm focused on my mind how do I mentally get stronger believe in myself and have that motivation to do the things I need to do
