Find it hard to be optimistic

I just feel week to thinking forward and I feel that why should I be positive? Why should I think this way or not that way, I feel unloved maybe. Due to this, I have also been thinking a lot lately, things that doesn't matter also come to my mind. My mind is always sort of restless 😬

I tried spirituality, and it works for me but I still find it difficult to take rest and stop mind.
