Honestly never be afraid to ask for help. It is not a weakness but a strength.
Also there are always people who love you even if you don't think you deserve or need it.
I remember years ago when I was still in therapy I told my therapist that I felt bad asking my friends for help because a lot of them were also going through some bad stuff and she told me
“You know, sometimes people in crisis will enjoy helping. It can be a distraction from their own problems.”
And then the next week I reached out to a friend who was in the middle of going through something about what I was going through and my therapist was right. That friend jumped at the opportunity to help.
And I’ve realized since then that my own problems rarely have anything to do with my ability to help others with theirs unless I am literally having an attack of some kind at that moment. In fact, it is actually refreshing to work on other peoples problems with them sometimes. Listening to problems you’re not soaking in constantly and helping your friend is often something you just want to do because you care about them. And you don’t stop caring about people because you’re having a hard time right now.
So I guess sometimes inviting someone into your sinking ship does work actually.
