How do you get your life together if you know you have problems?

I went from sitting in my house and having bouts of agoraphobia to finally getting back out. And talking to friends. I have weird obsessions with certain topics or things like a tv show or movie but then the obsession stuck onto certain things in my life. Friendship ending, relationship starting. Like anything. I take things to heart so bad. And it’s like I went from one extreme of total isolation to the opposite end.

I don’t know what’s with me. I do know it’s incredibly hard to focus. And im in school, I’m trying to be a nurse. You’d think I wouldn’t have time for these compulsions or these things yet I do. My family always told me if I filled my schedule enough I won’t think of these things. I don’t wanna get into the themes I’ve had but it would be fear of contamination, fear of going certain places, etc. I then finished college and felt so burnt out that I didn’t do much for several months.

Then I got a surge of inspiration and I felt pressure so I applied for school and got in. And I saw my friends/ began a relationship. Yet things feel like they’re falling apart and I’m picking or obsessing over certain things. And I feel like my grades are plummeting and I’m just stressed yet I can’t stop doing what I know is harming me.

I got in touch with mental health support but I feel like the damage is done. I don’t know what to do but I feel incredibly sad/ unmotivated while also feeling like I’m spiraling. I’m not sure where to begin with fixing this? I’m ruining my friendships and I don’t really recognize myself.
