It is very difficult to deal with caretaking a sick family member without trying to reach another goal at the same time. If the critical family member would take your parent to dialysis, you could concentrate on job hunting. I suppose this isn’t possible.
I am older and retired, tho sometimes I look for a job to have more to do than to find doctors for my husband. It is very difficult because you have to focus completely to get a job. If possible, get someone to help you with your family member.
Do you have a definite job you would like to get?You should probably go for an informational interview, getting information from someone experienced about how to get into that field. The person you talk to could be encouraged to be your mentor. You could offer to take them to lunch throughout your job search.
I don’t know if its international, but in the States it is very important to put your information on Linked In, a website for networking for jobs. Most professional people in the US have their information on Linked In. Or you could have your own website with all your information. This would also show your technical skills.
One thing that young people have difficulty with is being assertive enough. You know you are good, be assertive. Promote yourself. Good luck!
