The Repeating Thought

I am very sure your son needs you around no matter what.
As his parent you mean a lot to him, no matter what might happen to you two.
Even if you can’t be with him much because your wife has him, you are still a very important person in his life.

Ofcourse your parents would care. Even if it doesn’t seem so, they do care.

These sort of meds are usually a gamble, they effect each person and condition differently, you have to try until something works.
You’re not a disappointment. You’re trying your best and right now things are rough but eventually you’ll manage.

Don’t let your bad thoughts win. I know it’s hard and i know they insist and i know you can’t just shake them off, but,
you do have something to lose. If you are gone you’ll never see either of them, your son and your parents, ever again.
You have your son who needs you, and i might not know what’s been going on with your wife and why she’s giving you a hard time, but there’s always a chance she’ll rethink everything or realise how much you mean to her or at least to your son’s life, and soften herself a bit.

I’m sure your son loves you regardless though, and needs you around even if you were forced to stay away from him for a while.
