I have major depression and PTSD, and I'm beginning to doubt myself if I can actually work for myself to earn money and survive in the future.

I've been job hunting for 3 months now and nothing good came out of it. Even though I came from a reputable industry it seems like I'm still not good enough (which is normal since I know most university students aren't really 'industry-ready') but to be rejected for several intern positions?.. I'm totally wrecked.

I can simply do freelance work or something like that since I'm a designer, but my moodiness and lack of control of my triggers just make me feel doubtful of myself. My depression is taking a toll these past months and I can't seem to produce anything for my portfolio, it's hard to make myself eat, let alone finish my work.

Can I really survive? How can I earn money with this instability? I don't even trust myself anymore.
