Pray in salah and seek Allah's help, know the meanings of duas and surahs which are recited in salah. Start slowly,take your time in offering salah,don't take it hard on yourself,offer one time salah at first day ,and when you feel that you are ready to offer two times salah in a day and you are comfortable in doing so then offer two times salah in a day,...
Walaikum Assalam wa Rahmatullahi wa Barakatuhu,
Don't feel like that. It may be a trick from Shaytan. Pray Salah and ask help from Allah. Ask Allah to forgive your sins, ease your difficulties.
If you don't pray you would be sinful and Shaytan will be happy.

I hope it will be helpful. May Allah ease your difficulties. Aameen
