I am not diagnosed with OCD but my psychologist says I have some behaviors of it. I was mentally sick a couple months ago and ever since then I am very negative on myself and have bad thoughts of Allah. Also questioning if they are only thoughts, but I guess it is just thoughts. Do you have advise?

Ustadh AbdulAziz al-Haqqan
These thoughts that you hate are not held against you, the Companions had such thoughts and the Prophet ﷺ called hating them clear faith, so do not engage with them and keep up your treatment.
