Unstoppable overactive toddler

Hello.

My LO is 15 months, he is very active and always upto something, like I worry when he is sitting cause that's not his normal. You stop him from something and he is already on the next, unstoppable.

Since he has started walking my anxiety has been crazy, I'm woozy all the time and recently with his tantrums I have started loosing my patience just cause I'm buzzing inside.

I live with my in-laws and the constant advices and suggestions bother me alot. I feel I'm not a good mother and not doing enough for my child.

Any suggestions on how to cope and engage my child and discipline him
