Freelancing isn't always easy but it's a decent supplement and I conduct myself as professionally as possible. No one is hiring substantially in my area at the moment and I thank God I have this to lean on. I keep reaching out, researching, and networking. I voice my needs and concerns and people reach back. Sometimes things turn up, other times not. It's like scattering seed.
Also, if you're concerned about the quality of your portfolio I saw several sites, articles and youtube channels on the subject. Mayhaps you want to check those out? I was also looking at Image and Dark Horse comics and their guidelines for accepting work. I started scrapbooking possible leads and investigating them one-by-one.
It seems the challenge all artists face is sustaining ourselves so we can literally buy the time we need to work. It makes me hate money but unfortunately we need it in this world. It's just getting rid of that nagging financial pressure >_<
Are you familiar with Patreon? Fellow deviants recommended it to me. It's not a guaranteed substantial living but it is a useful seed to toss out there. It certainly worked out awesome for Tracyjb. I have mine here as a tip jar of sorts
