Feeling something mentally disturbed.

Since more than 9 months I am working from home because of COVID. Before COVID situation I used to split my time between work and family. But now I can't follow my time, I couldn't manage house work and office work in parallel. Lot time spending time inside home makes me so depressed and anxiety. No proper sleep schedule, no proper food time, too much stress, family problems, anxiety, depression, weight gain. I feel like a behavioural change sudden anger for no reason getting tensed showing anger on family. Frequently fighting with my wife showing signs of male dominance and When my 1 year old kid cries I am getting irritated too much becoming uncontrollable my mind is totally becoming evil. I know This is not good even though I try to control my self I could not do it and I am too worried if my behaviour will harm my family. I was not like this before and I am not sure how to handle this. I feel like want to be alone. I need advice how to come out of this situation.
