I actually went through bed bug psychosis I think and still am tramuatized from my experience with it. I did so much fucking research on bed bugs and body lice and other ectoparasites that can seriously cause damage to humans like rat mites, and batbugs (bed bug cousins, can barely tell the difference without a microscope) that I could pass college level courses on them easily. It hurt me in the long run doing that though and I fully believe it caused a lot of my mental health issues regarding being ocnstantly worried and having PTSD about catching them again. And in regards to dipping your head in alcohol for lice. Yes, that's head lice. Head lice are easy to get rid of though with over the counter or prescription hair lice medicine. The issue lies with people not washing their bedding/pillows/everything your hair touched afterwards because they can survive without a host for 2 days to three days. Body lice are relatively easy to get rid of as well but once again the issue lies with you have to wash your clothing (They live in clothing but move to the body to feed on you) and everything your clothing and you came into contact with in water over 140 degrees farenheight. If that's impossible almost any dryer, especially the industrial ones on the highest heat setting for a half hour will kill any and every ectoparasite there is including bed bugs. But body lice are actually more of an issue to get rid of because they will live in furniture and your bed similar to bed bugs. unlike bed bugs though, they need to feed every two to three days as well so it needs to be a piece of furniture that sees a lot of activity. Public lice are the worst ones by far because those can infest your whole fucking body and you need prescription premethin cream to get rid of them.

Fun fact though, did you know the three different lices actually are biologically separate? They evolved on completely different paths, look it up! Just their traits and abilities are so perfect for what they need to survive that science and biology evolved them all to be so incredibly similar.

Not trying to scare anybody but the three most common places to pick up bed bugs are obviously hotels, libraries are #2 on the list, and public transportation is #3 on the list.

I have the same feelings emotionally and mentally..I still have no one in my corner for emotional support and I spent years and years when I had my own place before the place i got evicted from, letting my so called friends come over and vent their problems. I would cook for them, let them and their couch surfing asses stay in my extra bedroom/on the extra bed, and be their emotional support. No one was willing to return any of that at all when I wnet through what I did and that's what hurt the most. Honestly if you do end up on the streets, and you are having mental health issues, just go to your local county mental health authority or the ER and tell them you're suicidal and they'll throw you in either a crisis residential group home (they're like houses) or a psych hospital (those aren't actually as bad as they get the rep for being.) for a couple weeks. I pulled this a couple times when I couldn't stand the bed bugs and body lice at the homeless shelter anymore and they're actually really nice mini vacations. At the group homes they let you have your phone/laptop/smoke cigs outside at least here they do, but at the psych hospitals they take your electronics and they just give you a patch, that was the worst part, not being able to smoke cigs tbh. The food is decent and the staff for the most part is really nice and helpful. And I learned a lot of things from the groups at both the group homes and hospitals that helped me and still help me to this day. Hang in there brother.

Also, don't be ashamed to reach out to government programs for help. This is exactly what they're there for and why they are essential to society. In some areas of the country you can get right into a section eight housing or free housing (in an apartment/rental) for so long immediately if your area isn't experiencing a housing crisis. Unfortunately, most areas are and the waiting lists are extensive. But if i were you the first thing I'd do is apply for food stamps.
