How do you handle those things:
Feeling lonely?

Call or text someone.

Being truely alone?

I'm not.

Having no motivation?

If I feel demotivated, I ask myself why I feel like that and question whether or not I should even be motivated. Then I react accordingly.

Battling to find a purpose beyond surviving the day?

I don't battle it. I accept and acknowledge life is meaningless.

Feeling like you are being deserted or avoided?

I don't feel like this.

Feeling overwhelmed?

Take a break. Distraction.

Lots of what your feeling is normal. Why do you think it is bipolar causing these negative thoughts?
