1) I do not think anyone would want any sort of relationship with me, be it friendship or otherwise, so I don't look for it.
2) Do I think I should be in a relationship? Probably not, as I have been alone for so long that I am not sure I know how to anymore. (Like they say, use it or lose it.)
That said.
I do not know if it is good or not.
I think it would depend on whether the person can find someone who is not judgmental, willing to see them as more than whatever their diagnosis is or the medication they take, and can see past whatever issues they are dealing with.
I think it would take someone who can honestly see value in the person—someone who is not just talking but willing to back it up by standing side by side, back to back, with that person.
With that out of the way, if one is looking to have such things in their own life, they may want to prioritize stability first, especially if they are still dealing with their own life struggles.
What I mean is that they have
1) Stabilize their situation as best they see fit, and make sure their partner is stable and brings no unwanted stressors (there will still be life's standard stressors that are unavoidable).
2) Be willing to have an honest talk with each other, be understanding of each other's current situation (be willing to ask hard questions: are you both in therapy? (is it working, do you need your partner to go with you?), taking your medications, managing your hygiene, eating healthy, exercising), and if the answer is no to one or two of your questions, are you still willing to be part of that? (There are probably many other questions.)
Basically, I think one would have to find a partner who has been down the road you have in their own way so as to have a mutual understanding.
Sorry if my post is stupid, wrong, incoherent, or too long.
