When a person goes through a deep loss, especially the death of a parent, the mind can change in how it processes thoughts and emotions. Some people become withdrawn, lost in their own inner world, or emotionally distant, while still being able to manage daily tasks. This does not always mean a serious illness, but it does suggest that the person is struggling internally and needs support. In your sister’s case, the mix of zoning out, overthinking, unusual reactions, and changes in speech may point to unresolved grief, emotional overload, or a stress-related mental health difficulty. Since these changes have lasted for a long time, it would be wise to have her assessed in a calm and respectful way.

Mood changes are there, also associated behaviour complaints which can be taken care of by medicines and therapy.

Hi After losing her mother, your sister may be experiencing complicated grief with emotional withdrawal and occasional thought disorganization. Zoning out, laughing to herself, agitation, and unclear speech can happen when grief stays unprocessed for a long time, especially when someone is isolated. The fact that she still eats, sleeps, manages money, and enjoys drawing shows her basic functioning is intact, which is reassuring. The safest way is not to force “therapy” or label her condition. Approach it as emotional support or a routine mental health check, preferably with a psychiatrist or clinical psychologist, and go with care rather than urgency or fear. Early evaluation can help before patterns become deeper. Take therapy. You can connect with me on nine two six six seven two six zero six five.

Hi, From what you describe, your sister’s symptoms are not simply “low motivation” or normal grief. While the loss of a parent can trigger prolonged grief or depression, certain features you mention need careful psychiatric evaluation, such as: Social withdrawal and loss of functioning (not working for 2 years) Zoning out, excessive rumination about past events Smiling or laughing to herself Periods of agitation Speech sometimes becoming difficult to follow These can suggest possibilities such as: 1. Prolonged Grief Disorder 2. Major Depressive Disorder with psychotic features 3. Trauma-related dissociation 4. Early psychotic-spectrum illness (especially given disorganized speech and behavior at times)

Hi, Staying withdrawn or remaining to self, smiling to self, agitation and speech that becomes hard to follow can be an indication of underlying psychotic disorder. In such conditions the person himself is not aware of the problem with them so the family members need to play a pivotal role. You need to get in touch with a nearby psychiatrist in person and discuss regarding assessment and management

She needs to seek professional help

I’m sorry you’re facing this. Your sister’s symptoms may be due to prolonged/complicated grief, possibly with depressive features. It’s reassuring that her sleep, appetite, and daily functioning are largely intact, but some behaviors do need professional assessment. The safest approach is not to force therapy. Present it as a routine mental health check-up, preferably with a psychiatrist, in a calm and supportive way. An online consultation can also be a gentle first step. Early evaluation can help and is often very beneficial.

Sister could be going through bereavement process due to the loss of mother . It is important for her to be open about her feelings and if willing then have a consultation so that we can decide whether psychotherapy or medication management is needed .
