I've struggled with depression my entire life. My brother killed himself when I was 11. My dad has abused drugs and is mentally ill and my mom doesn't speak to me anymore. I have incredible friends and the most loving boyfriend but I don't feel like I'm enough for them anymore. I'm lazy, awkward, and can't contain my emotions. I don't know what the fuck to do. I'm in a hole right now and all I can think about is the time I could have successfully killed myself if I didn't chicken out and tell my dad when it happened. Things have gotten better but my mental health is deteriorating and I feel like pulling the trigger or just disappearing would be my best bet. I don't want to be a burden anymore.
I'd like to start of by saying that i'm very sorry about all of the terrible things you've had to go through in your life, it sucks really bad.
Still, just because life started off badly, it doesn't mean it has be like this forever, life can change for the better, the problem is that it's hard, and to a lot of people, it can seem impossible (We are on a suicide forum afterall).
I'm not very good at giving advice, but i'll try my best at expressing what i think you can do.
First, i think relationships are the biggest thing you can focus on right now.
Family is the most obvious place to start. You've mentioned that your mother doesn't speak to you anymore, what happened between you two? (I know this is very personal, so i understand if you don't want to give details), perhaps reconnecting with her could make you happier somehow, depending on what you feel about her.
With your dad, you've mentioned him using drugs and being mentally ill, however when you "chickened out" (I don't like this expression tbh, to me suicide takes more courage than people give it credit, you're braver than you think) you told him, so i assume you at least trust him and like him somewhat, tho i can't say that for sure, but again, same thing i said about your mom, maybe trying to spend more time with him and even help him overcome his troubles (Drug addiction and mental illness) could give you more purpose and fullfilment, for both of you actually.
Now, where i really want to get at, you've mentioned incredible friends and a loving boyfriend, but you feel like you're "not enough for them anymore", i know we don't really know each other, but you've got to trust me on this one, there's no such thing as not being enough for the people that like you, or being a burden.
When people like you, or even love you, it doesn't matter what you think about yourself, or if you feel like you don't deserve that love, it's still real, and it's a beautiful thing.
If you're insecure about how your friends and boyfriend feel about you, be transparent and talk to them about it and, if you can, maybe even open up about your mental health, they could prove to be really helpful, i'm sure of it.
Like i've said, i suck at giving advice, i personally feel like they're generic and i'm insecure about them not really helping anyone, or even making things worse, but this is what i could think about when reading what you've written.
I seriously hope it can help, and i can't wait to read your reply (If there is any, i don't want to pressure you into writing one if you don't want to), i want to know more about the details of your thoughts and relationships so that i can help in the best way i can, cheers.
