@Magi_Kanus Dealing with self-doubts is very difficult, I'm currently experiencing myself. I haven't found a solution either, but I know that if I give up now, I won't be able to encounter happier times. Because I'll never know what the future looks like if I stop now. And even if that's the only thing I'm holding on to, it's enough to make me stay. Enough to make me stand through all this. I can't tell you to adapt the same view as me and I won't, but keep in mind that nothing is only ever bad, even if it feels like it all the time. Bad things seem to overshadow all the memories you have of the last weeks. But there were always some small, happy ones, even if you forgot them.
Don't give up on yourself. It's okay to feel bad about it. It's okay if you feel consumned by it. But there will always be some light in the darkness. There were happy times, and they will come again. And sometimes the latter just needs time. But you have achieved things, and by standing through this you keep achieving something. It shows that you're strong, even if it makes you feel weak.
