I am so sorry to hear about your experiences. It seems like you are trying your best to help yourself through meditation. It is wonderful that you have an insight about your problem. However, there might be a few things that you might have noticed that are different than they were before. You might not be able to enjoy the things that you once enjoyed doing. It might be difficult to even just get through the day. Your difficulty focusing can also be a trauma response.
Have you been reliving any of these experiences?
Have you lost or gained weight since your divorce?
Are you getting good sleep? (Falling asleep within 30 mins and not waking up more than twice in a night)
1) If you are noticing any of the above along with your thoughts and anxiety then you are probably not yet out of depression. In this case you should seek therapy to help yourself. Do make sure you discuss your relationship with your daughter with the therapist to understand single parenthood.
Your daughter is of a tender age. Therapy can be started at 3 years. Seeking therapy for her can help understand the impacts of divorce on her young mind. After all she must be grieving loss of parent and can start blaming you for loss.
2) Whether to allow your child to meet her father or not really depends on the situation. The children usually tend to blame themselves for the divorce therefore depriving them of parental love is not appropriate unless necessary. This needs to be discussed further. (Maybe through online consultation)
