How will I overcome loneliness after separation of a really bad breakup?

I am sorry to hear about your breakup. I know its not always the wanted answer, but it takes time to get back to your "normal" self after a breakup. Breakups are losses and when going through one you can experience grief symptoms such as trouble sleeping, sadness, etc.

Below are some things that you can try to help cope with your feelings:

Try journaling by writing out your thoughts so they don't just stay in your head. Often times it can difficult to fall asleep because nighttime is when thoughts become worse. You may experience ruminating or repetitive thoughts. Journaling can be helpful with this. Try a brain dump at night by getting all of your thoughts on paper.

Spend time with your support system (friends and family) or work to build a support system. If you need help building a support system, try a new hobby or volunteer somewhere to meet new people. 

Do things you enjoy doing. Think about the things that have brought you joy in the past. It may take some effort to get back into the habit, but doing things you enjoy can be helpful.

Spend time outdoors either sitting or walking. Being in nature is healing.

Incorporate mindfulness into activities. Mindfulness is focusing your awareness on the present moment, acknowledging your feelings, thoughts, and bodily sensations. When outdoors, it may be helpful to try a grounding exercise: 5 things you can see, 4 things you can feel, 3 things you can hear, 2 things you can smell, and 1 thing you can taste. This grounding exercise can be done in your head. Think through these things. Its a great exercise to help put you in the present moment. You can also try using an app like Calm or Insight Timer to help with mindfulness exercises. 

Finally, if you see that the coping strategies are not working and things are getting worse, that may mean that it is time to meet with a therapist. A therapist can help you process what you are thinking and support you through this life transition. 

I hope this information has been helpful to you.
